Electromagnetics are used to create (strong) magnetic fields. This has many applications, from MRI to see brain activity to determining molecular properties to making frogs fly.
nothing
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
Probably a metal hooker
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.
many people uses an electromagnet when working.
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?
