Are Neodymium Magnets Safe for Cell Phones?

Anyone who has worked with or is close to magnets has likely been made aware of the many health and safety hazards. One advice that has always been given is to keep magnets away from electronic devices such as laptops, credit cards, and even phones.

So, do phones and other contemporary electronics risk magnets’ damage? If this is the case, what dangers do they provide, how powerful must a magnet be for it to damage a phone, and which components of the device are most at risk of harm?

The whole concept, as discussed, can be traced back to ancient pieces of technology in which data was stored magnetically by employing small amounts of iron. This practice of ancient technology has been around for quite some time.

However, because of the steady stream of technological improvements, it is quite improbable that magnets would interfere with or harm a smartphone. However, this is contingent on the magnet and how you use your phone or what you need to perform.

What Effects Can a Magnet Have On Your Cellphone?

In the present era, almost everyone has a smartphone. Although these devices are indispensable in our personal lives, they are also more important in our professional lives. It is thus crucial to be aware that a strong magnet will not delete the data on your phone.

Magnets, however, will not affect your smartphone because of how storage systems have progressed over the years. We hope this priceless information puts your mind at rest.

Solid-state drives, used in more recent devices, don’t rely on magnetism to store data; as a result, these drives are immune to the effects of magnetic interference.

Similarly, contemporary panels will either be based on LCD or LED technology, eliminating any possibility of magnets interfering with their operational capabilities. Direct contact with your phone’s screen is required to shatter it with a magnet. For example, you might try dropping the magnet on the screen.

How Might the Attraction of Neodymium Magnets Affect Your Applications?

Even if we can guarantee the security of your phone’s display and its data, the compass will not be one of the components that will remain intact. Even while many individuals will immediately believe that they do not use the compass app, the harm caused by this might have a knock-on impact on other applications.

Stronger magnets like neodymium magnets can affect the internal magnetic sensors that are housed inside a smartphone and can also magnetize some of the steel that is included inside the device.

Stronger magnets can affect the internal magnetic sensors housed inside a smartphone and magnetize some of the steel that is included inside the device.

In addition to negatively impacting your phone’s compass, this might also impact other applications, such as maps or any app that requests your location. These applications may become very difficult to use if the compass on their installed device gets corrupt.

Because magnetometers are often located closer to the top of a device, it is recommended that any magnetic attachment that you want to connect to your phone, such as in a case, be placed closer to the bottom of the device. This is because cases typically cover the top third of a device.

However, for a magnetic attachment to cause interference with a phone’s compass, the item would need to have a powerful magnet, far more powerful than the magnets found in most phone covers. That is to say, and it is quite improbable that magnets of the size and kind usually found in phone accessories would not cause harm to a smartphone.

How to Protect Your Phone from Magnets?

After reading about the horrible consequences that magnets may have on your prized smartphone, your mind is racing at the prospect of something similar happening to your gadget.

Fortunately, there are several precautions you may take to protect your phone from magnets that might damage it.

Tips for Phone Magnet Protection:

  • Select the best phone cover
  • Sticking magnets on your phone is not a good idea.
  • Keep magnets away from your phone.
  • Back up the data on your phone.

The first piece of advice on the list above suggests that you should “choose the right phone cover.” Certain phone covers will use magnets and metal components to clarify this broad statement for ornamental or practical reasons.

While most of these magnets are not powerful enough to cause instant harm, they can gradually wear out the inner components of the phone if they are in close contact for an extended period.

If you own an iPhone or any other comparable Apple electronic gadget, you won’t have to worry about this if you buy your phone covers straight from them.

With the knowledge of the harmful consequences that may occur when smartphones and magnets come into contact, Apple has developed its Case Design Guidelines, which do not encourage the use of magnets or metal components.

In addition to Apple’s rules, case makers must observe a set of restrictions regarding magnets and metal. Because these components might interfere with smartphone functionality, the built-in magnetic compass of each phone must not be influenced by the cases they are constructing.

The following suggestions may seem apparent, yet they must be followed. Always keep your phone away from magnets whenever possible, and never attempt to place magnets anywhere on the outside of your smartphone.

Finally, create a habit of regularly backing up your phone’s data to another device to prevent any accidents if anything like this happens to your phone.

Magnets, no matter how large or small, may harm a smartphone’s inner workings. Even the tiniest magnets may progressively wear out these components, causing your gadget to fail. However, you should be OK if you can do everything it takes to keep your smartphone secure.

Are Neodymium Magnets Capable of Wiping Off My Phone?

One of the most common misconceptions about strong magnets (neodymium) and phones is that a magnet could potentially erase everything from your phone, including your precious photo memories and important contacts. Is it, however, a serious possibility? The idea behind this stems from hard disk drives, which use neodymium magnets to switch from reading to ‘writing’ data; thus, the major worry is that a powerful magnet could tamper with this and switch to writing, potentially overwriting or even erasing existing data.

To begin, we’d like to point out that to cause this shift, you’d need an extremely big and powerful magnet that was also extremely close to the hard disk drive.

Second, the storage available in today’s smartphones is a long cry from the standard hard disk drives seen in desktops. Mobile phones typically use flash drives to store all of your data. The good news is that these do not contain any magnetic components, so no amount of magnet will interfere with your data!

Will a Magnet Interfere with My Phone’s Digital Compass?

A digital compass is incorporated into iPhones and most Android devices. Like more traditional compasses, this compass is used by the phone to help give you the most accurate directions. As a result, a strong magnetic field, such as that produced by strong neodymium magnets, has the potential to affect your phone’s compass. However, if your phone is affected by a magnet and the compass is compromised, you should receive an alert, and thankfully, there are steps you can take to correct the situation.

Can Strong Magnets Harm My Phone’s Speakers?

In recent years, mobile phone speakers have grown more high-tech, significantly increasing overall sound quality. The speakers on your mobile phone, like those on your television, computer, or radio, are powered by magnets. So it’s fair to be concerned that additional magnets will negatively impact your speakers. Fortunately, no matter how powerful your neodymium magnets are, they will not destroy the magnets in your phone’s speakers.


In conclusion, it appears that neodymium magnets aren’t as bad for our cell phones as we believed! Aside from the danger of a cracked screen, the only way magnets may impact your phone technologically is by interfering with the magnetic compass. However, this is only achievable if you use a powerful magnet in close contact with your phone over an extended period; it can also be readily repaired. Now that we’ve put your mind at ease, we have a large selection of Neodymium magnets for all ranges of the project you’re working on. Shop our whole selection of magnets.
