When or why are magnets safe to use now?
In: Technology
Old computers used magnetic media for storage which meant your hard drive or floppy discs could be erased if you had a magnet sitting on your computer. CRT monitors used a magnet to aim the beams for drawing the picture on the screen, so magnets would distort the image, and if left long enough would damage the picture tube.
Modern technology uses solid state storage and monitors use pixels (LCD, OLED, etc), which is dependent on an electric charge stored in a transistor, rather than the direction of a magnetic field, so weak magnets don’t affect them. You would need a magnet strong enough to induce a strong current in a computer to flip bits, one much stronger than generated by a small magnet.
