Magnets are Destroyers of Electronic Devices? Rumor!
Although the smart phone or other digital devices are far more superior to the older generations now, people still worry about the problems like distortion of screen, or deletion of important files when they are close to permanent magnets. It seems that the magnets are destroyer of smart phone. Is that true?
According to the experts, why there are such misconception is just because the magnets exactly damaged the electronic equipment before, for example, the CRT display and television were easily be distorted by strong magnetic filed. However, nowadays, there situations will not come again.
On the one hand, actually, there are small neodymium magnets inside the phone itself to achieve some vital function, like the magnetic-induction wireless charging system in Apple Watch. Thus, it proves the permanent magnets will not affect the inner components of the electronic devices.
On the other hand, people worries the magnets will delete the data in the HD. But it is said by the experts that only the data recorded via permanent magnetic materials, such as cassette, floppy disk, video tape, credit card, etc. can be deleted by magnets. To prove this, an engineer attached a large magnet on the working HD, and it shows that the stored data are still in good condition, even the internal structure of the HD are damaged. Thus, this argument is also incorrect.
In a word, permanent magnets are not destroyers to the digital equipments; on the contrary, they can make these devices multi-functional.
