Warnings about magnets and gadgets have been passed down like tech folklore, often without much explanation. The reality is more nuanced: some electronics are genuinely vulnerable to magnetic fields, while most modern devices shrug off everyday magnets without a scratch.
To separate real risk from myth, I am looking at how different components actually work, when a magnetic field can interfere with them, and where the line sits between a harmless fridge magnet and the kind of field that can corrupt data or disrupt life‑saving medical implants.
Why magnets and electronics got tangled in myth
The fear around magnets and electronics traces back to an era when screens and storage literally depended on magnetized parts. Early televisions and PC monitors used CRT technology, and those CRT displays relied on magnetic fields to steer electron beams, so a strong external magnet could distort colors or warp the picture, which is why older sets were so sensitive to a nearby magnetized object, as explained in detail in a CRT focused breakdown. At the same time, floppy disks and early hard drives stored bits as tiny magnetic domains, so a powerful enough field could, in principle, scramble that pattern.
Those experiences hardened into a simple rule of thumb that magnets and electronics do not mix, even as the underlying technology changed. Modern TVs and PCs, alongside phones and tablets, no longer rely on the same exposed magnetic storage or beam steering, and reporting on current hardware notes that the odds of a typical household magnet doing any harm to these devices are extremely low, a point underscored in a recent analysis of modern TVs and PCs. The myth, however, has lingered, often without distinguishing between legacy gear and the solid‑state, shielded components that dominate consumer electronics today.
How magnets actually interact with electronic components
To understand what is at risk, it helps to separate the different ways a magnetic field can affect electronics. Some components, like spinning hard drives and magnetic tapes, use magnetism to encode data, so a sufficiently strong external field can realign those domains and corrupt information, which is why experts still list hard drives, RAM chips, power supplies and other electrical parts as potentially vulnerable to magnetic fields in technical Answers. Other parts, such as inductors and transformers, rely on magnetic fields to operate but are usually encased and shielded, so they are less likely to be disturbed by the weak fields from everyday magnets.
There is also a difference between static magnetic fields and changing electromagnetic fields. A static field from a permanent magnet tends to interact with components that store or sense magnetism, while rapidly changing fields from motors or wireless chargers can induce currents in nearby circuits. Modern devices are designed with this environment in mind, and without these magnetic components there is no way for many circuits to function at all, a point that is highlighted in a technical explanation of how magnetic components are built into electronics. The key question is not whether magnets and electronics can coexist, but whether an external field is strong and close enough to disturb the specific part that is sensitive.
Old tech versus new: CRTs, tapes and solid‑state drives
The starkest contrast is between older magnetic media and today’s solid‑state storage. In the past, floppy disks, magnetic tapes and early hard drives could be wiped or degraded by a powerful magnet, which is why people were warned to keep such media away from speakers or large permanent magnets, a point echoed in an Mar discussion that notes how old magnetic media could lose all data if exposed to a strong enough field. CRT televisions and monitors, which used magnetic deflection to aim electron beams, could show rainbow blotches or warped images if someone held a magnet to the glass, a problem that simply does not exist on LCD or OLED panels.
By contrast, solid‑state drives and flash memory in phones, tablets and USB sticks store data as electrical charges in tiny cells, not as magnetized regions, so a static magnetic field does not have a direct way to flip bits. Data recovery specialists point out that magnets will not damage solid‑state drives, even though strong magnetic fields can still destroy older magnetic media and are sometimes used to securely erase data on those legacy devices, a distinction laid out in a technical note on Do Magnets Damage Solid. The same logic applies to USB sticks, which typically sit inside plastic or metal housings that protect internal components, and guidance for consumers stresses that while certain media such as magnetic tapes remain vulnerable, a magnet would need to be extremely strong and very close to have such an effect on modern USB based devices.
Everyday magnets: fridge clips, phone cases and speakers
In daily life, the magnets most people encounter are relatively weak: fridge clips, magnetic knife strips, earbuds, phone cases and laptop covers. For modern phones, tablets and laptops, simply placing a small magnet nearby or using a magnetic accessory is not enough to corrupt data or fry components, because the internal storage is not magnetic and the circuitry is shielded. A detailed explainer on magnets and gadgets notes that just leaving a fridge magnet on the side of a PC case or television will not alter an established electromagnetic current or erase data, a point made explicitly in a breakdown of why a fridge magnet is harmless in that context.
That reassurance lines up with how people actually use their devices. In one Comments Section about N35 Magnets and a Galaxy Fold phone, users point out that magnets have little to no effect on modern electronics in normal use, which is consistent with the engineering behind these products. Even so, manufacturers sometimes warn that very strong magnets in accessories can interfere with specific features like compass sensors or wireless charging coils if placed directly over them, so it is still wise to follow official guidance on where and how to attach magnetic mounts or cases.
When magnets really can cause damage
The fact that most consumer magnets are harmless does not mean magnets are universally safe around electronics. Strong permanent magnets, especially neodymium types used in industrial settings or powerful hobby projects, can generate fields intense enough to affect magnetic media, analog sensors and some precision instruments. Safety guidance for workplaces that use such magnets notes that a strong magnetic field can damage electronic devices and recommends keeping a distance of at least 20 cm from all electronics to avoid interference, a rule of thumb spelled out in a set of Key rules.
Laboratory and aviation environments are even more cautious, because certain instruments are designed to sense very small magnetic changes. Research safety guidance warns that strong magnetic field producing magnets can damage magnetic media such as credit cards and tapes, and can also disrupt compasses and magnetometers of aircraft, which is why such magnets are tightly controlled in those settings, as outlined in a Users advisory. In other words, magnets can absolutely cause real damage, but the risk is concentrated around very strong fields, sensitive instruments and older magnetic storage, not the casual magnets stuck to a kitchen appliance.
Medical and personal safety: pacemakers, injuries and handling
Beyond gadgets, magnets can pose serious risks to people, especially those with implanted medical devices. Safety specialists emphasize that persons with cardiac pacemakers, hormone pumps and other implanted devices should not be brought into close proximity to strong magnets, because the fields can interfere with the electronics that control those implants, a warning spelled out in guidance that begins with the phrase Simple Precaution and continues with We Recommend the Following Safety Considerations for handling magnets near vulnerable individuals, as detailed in a Simple Precaution advisory. That is why hospitals and MRI facilities screen patients and staff for implants before exposing them to very strong magnetic fields.
Physical injury is another underappreciated hazard. Strong magnets can snap together with enough force to pinch skin or even break bones if body parts are caught between them, and small magnets can be a choking hazard or cause internal damage if swallowed. Magnet safety guidelines warn that the attraction of magnets in the body may cause serious injury and require immediate medical care, and they also caution against trying to machine or drill the magnets because fragments can become dangerous projectiles, as highlighted in a Magnets safety bulletin. For anyone working with large neodymium blocks or arrays, the bigger risk is often to fingers and eyes, not to the nearby smartphone.
Safe distances and practical rules for home and office
For most households, the key is not to eliminate magnets but to use them with a sense of proportion. Consumer guidance on permanent magnets notes that various objects are sensitive to static magnetic fields, yet also points out that digital cameras, mobile phones, iPhone, iPod, iPad and similar devices are generally safe if kept away from strong magnets, and recommends maintaining a reasonable distance between such devices and very powerful magnetic assemblies, as laid out in a FAQ that lists What devices are at risk. In practice, that means a magnetic phone mount on a car dashboard is fine, but stacking rare‑earth blocks directly on top of a spinning hard drive or an old VHS tape is not.
Workplace safety rules echo that approach with more specific numbers. Occupational health guidance for neodymium magnets advises people with pacemakers to keep a safe distance and recommends that strong magnets be stored and used in a way that keeps them at least 20 cm from all electronics, reinforcing the idea that distance quickly reduces risk, as summarized in a set of People focused precautions. For home users, a simple rule works: if a magnet is strong enough that it is difficult to pull off a metal surface with one hand, treat it with respect, keep it away from legacy magnetic media and medical implants, and avoid placing it directly on top of sensitive sensors or spinning drives.
What experts say about the “magnets kill phones” myth
Technical writers and engineers have been pushing back on the blanket claim that magnets will wreck modern electronics, arguing that the myth is rooted in outdated hardware and a misunderstanding of how current devices store data. One detailed explainer notes that in actuality, while magnets can be mildly hazardous for some devices, the lion’s share of concern is a myth rooted in older technologies and in scenarios where a magnet is strong enough to physically move components around or erase vital data, a point made explicitly in a section that begins with the words In actuality and goes on to describe how magnets can be mildly risky only in specific contexts. That perspective aligns with the way manufacturers design phones and laptops, which already contain internal magnets for speakers, haptic motors and covers without self‑destructing.
The same message has filtered into more casual commentary. A widely shared post on social media notes that while extremely strong magnets could still damage electronics, it is a myth that regular consumer‑grade magnets will corrupt or destroy a modern phone, computer or modern TV, a claim spelled out in a statement that begins with the word While and directly addresses fears about everyday magnets and screens, as seen in a While post. When I weigh that against the engineering details and safety advisories, the pattern is clear: the blanket warning that any magnet near a gadget is dangerous is not supported by how modern electronics actually work.
How I would handle magnets around different devices
Given the mix of myth and real risk, I find it useful to think in categories rather than one‑size‑fits‑all rules. For legacy gear like CRT televisions, VHS tapes, cassette decks and spinning hard drives used for archival storage, I would keep strong magnets well away, because those devices rely on magnetic fields in ways that can be disrupted, a point that is reinforced in technical discussions of Hard drives and other components that can be vulnerable. For modern phones, tablets, SSD‑based laptops and game consoles, I am comfortable using magnetic cases, mounts and accessories, while avoiding placing unusually strong neodymium blocks directly on the device or its charging coils.
For people with medical implants or who work around sensitive instruments, I would err on the side of caution and follow institutional safety rules, including the recommendations that persons with pacemakers and hormone pumps avoid close proximity to strong magnets and that unnecessary handling of powerful magnetic assemblies be minimized, as outlined in guidance that begins with We Recommend the Following Safety Considerations and urges users to Avoid uninformed handling. For everyone else, the practical takeaway is straightforward: ordinary household magnets are not ticking time bombs for your electronics, but industrial‑grade magnets and legacy magnetic media still deserve real respect.
