What is an electromagnet? An electromagnet is a magnet that runs on electricity. An electromagnet works because an electric current produces a magnetic field. If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops.
Electromagnets are used to control the switches in relay. This is important especially when it comes to things like making a telephone call. The first telephones made use of a type of relay called a reed switch it not only helped to connect calls but performed the rudimentary logic and memory functions.ou can say that the electromagnet made much of the modern age possible harnessing electricity as a practical force in the same way that mankind used windmills and dams to harness wind and water.
