Question

Differentiate between bar magnet and electromagnet

Answer 1

$Permanent\left(Bar\right)magnet$

$\left(1\right)$hey are permanently magnetized

$\left(2\right)$These are usually made of hard materials.

$\left(3\right)$ TThe strength of the magnetic field line is constant. it can not be varied.

$\left(4\right)$The pole of permanent magnet can not change

$\left(5\right)$Example of permanent magnet is Bar Magnet

$Electromagnet$

$\left(1\right)$ These are temporary Magnetized.

$\left(2\right)$ They are usually made of soft materials.

$\left(3\right)$The strength of the magnetic fields can be varied accordingly to our need.

$\left(4\right)$ The poles of an electromagnet can be altered

$\left(5\right)$ Example of a temporary magnet is solenoid wounded across a nail and connected to a battery..
