Most commercial drones have 4 motors w about 12 magnets each.
Some others:
electric bikes, electric skateboards, power tools, blow dryers, iPad cases.
If I recall correctly, one of the earlier iPhones was basically held together w rare earth magnets, with the screen module magnetically stuck into the case. Can't find info to verify this though, so take it w a grain of salt.
