What is electromagnet and its uses?
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. Electromagnets are used in millions of devices around the world, from hard disk drives and MRI machines, to motors and generators.
Why are electromagnets useful?
Electromagnets are useful because you can turn the magnet on and off by completing or interrupting the circuit, respectively. An electromagnet is the same way, except it is “temporary” — the magnetic field only exists when electric current is flowing.
Which activity uses an electromagnet?
In the home, by far the most common use of electromagnets is in electric motors. Think of all of those bits of electrical equipment with some kind of electric motor: vacuum cleaners, refrigerators, washing machines, tumble driers, food blenders, fan ovens, microwaves, dish-washers, hair driers.
