Question

what is electromagnet and solenoid in simple words​

Answer 1

Answer:

A solenoid is a coil of wire wound on a cylinder, that has a length that is large compared with its radius. A solenoid is a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. An electromagnet is a magnet that runs on electricity.

Answer 2

The branch of physics that covers whole/universal study of electricity and magnetism is called electromagetism.
.... a coil made by a conducting wire wound closely and seperately in a form of cylinder is called solenoid
