Also some credit cards have warnings to not put near magnets, but maybe the magnet's not strong enough to do damage
- moron4hire 11y agoMagnetic force decreases with the cube of distance from the source. Which is to say that it would take a ludicrously strong magnet at arm's length to do any damage to credit cards in their back pocket.
- GauntletWizard 11y agoThere's some context not obvious in that video: The machine as a whole fails, yes, but the only part of it that malfunctioned was the hard drive. The rest of the electronics in there are solid-state, and won't (okay, will be, but only minutely, and not enough to cause failure) be affected by the magnet. Your cell-phone is magnet safe.
