When the magnet's surface magnetic force exceeds a certain range, it will have an influence. In fact, there are magnets inside the phone itself to achieve some functions, such as wireless charging, which is affected by super-strong magnets. In addition, sensors inside the mobile phone, such as digital compasses, are also subject to display errors due to magnets. Magnets do affect the phone, but only ultra strong magnetism can affect some features of the phone. For magnets with small magnetic properties (such as small magnetic blocks on mobile phone holsters, magnetic mobile phone holders, etc.) generally do not affect the function of the mobile phone. Let's take a look at it together.
When using the magnetic mobile phone bracket, you need to attach a piece of iron (also called the magnetic piece) to the mobile phone, because the magnetic force of the bracket is not so large to directly suck the mobile phone. The magnetic piece is similar to the anti-magnetic speaker. The magnet is equipped with an iron shell that prevents leakage of the magnetic yoke. The magnetic field of the magnet does not leak outside the horn, forming a closed magnetic field.
The magnetic phone bracket brings a lot of convenience, regardless of the size and material of the phone. However, there are also disadvantages, such as the magnetic sheet attached to the back of the mobile phone affects the feel and beauty.
However, a good quality magnetic mobile phone bracket can be placed directly on the back of the hand (without stickers) and then put on the phone case, or it can be firmly sucked. Or stick the magnetic sheet inside the phone case, and then put a scratch-proof sticker on the back of the phone so that it does not wear the back of the phone.
The strong magnetic mobile phone bracket will interfere with the electromagnetic signal of the mobile phone and the magnetize iron-containing part inside the mobile phone, which will lead to the inaccurate navigation of the mobile phone, the distortion of the call quality, the running of the card, the serious data loss, the black screen of the screen, the sudden crash, etc. Therefore, the magnet bracket is harmful to the mobile phone.
