1. define what is electromagnetism?

Explanation:

Electromagnetism is a branch of physics that studies the interactions between electric currents and magnetic fields. It encompasses the phenomena of electricity and magnetism, which are closely related and can be unified under the theory of electromagnetism. Electric currents can generate magnetic fields, and changing magnetic fields can induce electric currents. This relationship is described by Maxwell's equations, which form the foundation of classical electromagnetism. Electromagnetic waves, such as light, are also a result of the interplay between electric and magnetic fields.

Answer:

Electromagnetism is the branch of physics that deals with the interactions between electric currents and magnetic fields, including the generation of magnetic fields by electric currents, the induction of electric currents by changing magnetic fields, and the propagation of electromagnetic waves.
