Rubber magnet is a soft magnet made of ferrite magnetic powder. It is more common in some daily necessities, such as bag seals, door seals of refrigerator cabinets, motors and so on. This type of magnet is more flexible to use because of its soft material. But at the same time, many people worry that long-term contact with these magnets will affect their electronic products, such as smart phones. The following editor will answer this question for everyone.
1. Screen, a screen made of a traditional cathode ray tube is easily affected by magnets. This is because a cathode ray tube display generates light by emitting a well-focused electron beam, which is deflected by a magnetic field to produce an image. Therefore, the external magnetic field first interferes with the magnetic field required to create the picture. However, LCD screens used in modern smartphones are generally not affected by magnets.
2. Data storage-The storage chip of modern smartphones (such as iPhone) is a "flash" drive, which cannot be erased with a magnet because there are no magnetic components in the chip.
3. Digital compass-The digital compass in smartphones such as the iPhone is like an electromagnetic compass. Its accuracy is like a traditional compass, and it is susceptible to strong external magnetic fields.
4. Location service-your smartphone uses the built-in GPS system to determine your location. Because GPS uses satellite signals instead of geomagnetism, it is less susceptible to electromagnetic interference.
5. Magnetometer-The magnetometer on your smartphone allows your device to detect the strength and direction of the magnetic field. It is compatible with the digital compass, but is also used by many other available applications. This special small device may be affected by strong magnetic fields.
6. Speakers—speakers on smartphones, like other speakers, require magnets to work, so they won’t be affected by external magnetic fields.
So, in short, in daily use, your phone may come into contact with magnets, such as magnets on magnet cases, shelves, wallets or handbags. These conditions will not cause any problems. Unless your smartphone is exposed to a strong magnet for a long time, it will damage the function of the phone's digital compass. Everyone needs to pay attention to this point.
