Question

What is the importance of the electromagnetism in the electrical machines?

Answer 1

1. Electromagnetism is the branch of physics that deals with electricity and magnetism and the interaction between them.

2.The basic law of electromagnetism is known as "Faraday's law of Induction."

3.Electricity can give rise to magnetism and vice versa. A very simple example is that of an "electric transformer." The exchanges take place inside the transformer that gives rise to electromagnetic waves. Another fact about these waves is that they do not need a medium to propagate although their speed is relatively slower when traveling through transparent substances.

4.Electrical home appliances use electromagnetism as a basic principle.
