Question

Give 1 use of eletromagnets​

Answer 1

Answer:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

Answer 2

Answer:

These are the uses of electromagnets:-

• The discovery of the electromagnet made possible the invention of electric motors and generators. Both of these work on a scientific principle called electromagnetic induction. This phenomenon was discovered by the scientist Michael Faraday.
• Electromagnets are used to control the switches in relay. This is important especially when it comes to things like making a telephone call.
• Only materials made of iron, nickel, cobalt or their alloys or naturally occurring minerals respond to a magnetic field. This has many practical uses. One use is sorting out metals. Since the elements mentioned are used a lot in manufacturing, using an electromagnet is an efficient way to sort these metals out.
• Used in lifting of massive objects.
• They are also used in transportation. Trains in Asia and Europe use electromagnets to levitate the cars. This helps them to move at phenomenal speeds.
