What is an electromagnetic force electric motors?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
What devices use electromagnets?
motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment are devices that make use of an electromagnet.
How can you use electromagnets in a real life situation?
Press a doorbell, for example, and electric current creates a magnetic field that attracts a ringer which strikes the bell. Relays are special electromagnets that function like automatic electrical switches.
Electromagnets In Other Common Devices

What is an electromagnet list any two uses?
(a) An electromagnet is a magnet that is created using an electric current, created by electricity. The two uses are: 1)Motors and generators. 2)Transformers.
What forces can be used in a motor?
A magnet exerts a force on current-carrying wire.
This simple device shows that when an electrical current flows through a magnetic field, a force is exerted on the current. This force can be used to make an electric motor.
How are electric magnetic fields used in motors?
Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. This is called the motor effect .
