Content

Magnetic fields

A magnetic field is a region in space where the influence of a magnet can be felt or detected, magnetic.

It is also a region where it exerts a force on other magnets. It’s a vector quantity.

Properties of magnetic lines of force

1. They originate from N-pole and end in S-pole
2. Two magnetic lines of force do not cross each other.
3. Where the lines of forces are close together, the intensity of the field is greater; where they are widely separated the…
