Derive the relation between magnetization of material and magnetic intensity
Answers
The magnetic intensity at a point is defined as the force that unit north - Pole experiences when it is placed in that field.
The intensity of magnetic field at P due to single pole is given by:
Intensity of magnetic field at P due to single north pole
Fig: Intensity of magnetic field at P due to single north pole
Intensity of Magnetic field due to a magnet at different points
In Longitudinal Position
Longitudinal Position
+/-m = Magnitude of south and north poles
r = Distance of point P from the centre of the magnet
l = Length of the bar magnet
∴ Intensity of magnetic field at pointP is given by,
Where M is the magnetic moment = 2*m*l
Case a: For a small magnet,
r2 ≫ l2
In Transverse Position
Transverse Position
Intensity of magnetic field at point P is given by,
When the magnet is of short length,
In Any General Position
Any General Position
