Currently strong magnets can still mess with pacemakers. Fun fact, some modern phones have magnets in them that can do that - be careful about resting your phone on your chest if you have a pacemaker. I think the wireless charging unit is to blame.
In terms of electrical interferance, there’s a lot that can go on. NFC transmits power indutively, cellular, wifi, sometimes with power sharing some you transmit electricty inducitvely too.
Apple phone’s have “mag safe” which is basically a magnet. Phone also have speakers and microphones and rumble motors and compasses, all magnetic.
