Answer 1

Answer:

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Answer 2

Answer:

EMF is the short form of Electromotive Force.

Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field. A generator or a battery is used for the conversion of energy from one form to another. In these devices, one terminal becomes positively charged while the other becomes negatively charged. Therefore, an electromotive force is a work done on a unit electric charge.
