Electromagnets are used in electrical devices like electric fan, motor, door-bell, electric buzzers, washing machines, etc., whenever strong magnetic fields are needed to be produced, electromagnets are used. These are used in electrically operated relay switches, and in nuclear research laboratories for directing charged particles. They are used in magnetic therapy given by physiotherapists, and also used in magnetic track trains.
An electromagnet is a temporary magnet which will only function is an electric current passes through its wires.
Electromagnets can be found in telephones, door bells, it is also used in MRIs, and it is also used to remove any magnetic object deposited in the eye during an accident or so.
a electromagnetism can produce motion . they can move together or more apart, depending on how their poles are arranged.
how does it works
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
Anything that uses electromagnets to work, such as credit cards, monitors, or hard drives.
NO,THEY ARE NOT......only uses a normal magnet at the door.

Electromagnets
Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
Electromagnets are primarily used to produce electricity Any large scale facility with lots of instruments will definitely have electromagnets in it. Generators in the powerhouse uses big electromagnets to produce AC voltage which is then transported for the commercial or residential use.
It uses electromagnets.
The answer is TV and door Bell !
like using laptop
1 a nuke uses electromagnets so does not fall apart they use it to keep the iron shell on and so it does not fall over and does not explode randomly.
