22. What do you understand by magnetic field?
23.
What do you mean by electromagnetism?​

Answer 1

$\huge\tt\purple{☘Answer}$

Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism.

______________________

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. ... At high energy the weak force and electromagnetic force are unified as a single electroweak force.
