A safety device that uses an electromagnet to shut off the circuit is called a contactor.
Probably a metal hooker
many people uses an electromagnet when working.
An electric motor uses an electromagnet to convert electrical energy into kinetic energy. The electromagnet creates a magnetic field that interacts with a permanent magnet, causing the motor to spin and generate mechanical motion.
Solenoid valves, magnetic contactors, motors.
True .
A galvanometer is a device that uses an electromagnet to measure electric current. It works by converting the current passing through it into a proportional mechanical deflection of a pointer on a scale.
A loud speaker can use electro magnets and i hope this helps =)
it uses electric force
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
Generator
Every electric motor and generator uses an electromagnet.
