MAGNETIC FLUX DENSITY

3 of 10

Magnetic lines of force are experienced in all dimensions around a magnet.

4 of 10

MAGNETIC FLUX DENSITY

The number of magnetic lines of force passing normal to unit area is the magnetic flux density of that region.

5 of 10

Magnetic flux density is greater at the poles of a magnet
