Question

What is difference between Solenoid. And electromagnet??

Answer 1

an electromagnet has a soft iron core
and a solenoid has a plastic or cardboard core

Answer 2

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. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
