Magnetic Intensity
The magnetic intensity at a point is defined as the force that unit north – Pole experiences when it is placed in that field. It is the amount of magnetic flux in a unit area perpendicular to the direction of magnetic flow. Magnetic moment per unit volume in a magnetic field is called the intensity of magnetization or simply magnetization. It is a quantity used in describing magnetic phenomena in terms of their magnetic fields and magnetization.
It is a vector quantity pertaining to the circumstance at any point under the magnetic influence (as of a magnet, an electric current, or an electromagnetic wave) measured by the force exerted in a vacuum upon a free unit north pole placed at the point in question — called also magnetic force.
The magnetic intensity defines the forces that the poles of a magnet experiences in a magnetic field whereas the intensity of magnetization explains the change in the magnetic moment of a magnet per unit volume.
