Answer:

A solenoid is a cylindrical coil of wire whose diameter is small compared to its length. When an electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a solenoid wound around a central iron core.

Answer:

SOLENOID

A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The term was invented in 1823 by André-Marie Ampère to designate a helical coil.

ELECTROMAGNET

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.

DIFFERENCE IS

The terms solenoid and electromagnet are closely related. The main difference between solenoid and electromagnet is that solenoid is the name given to a long and narrow helical loop of wire, whereas an electromagnet is a magnet whose magnetic properties depend on an electric current. Most often, electromagnets are constructed using solenoids.
