Study Notes

Magnetism

Magnetic length (M) is a concept in magnetism.
Geometric length (G) is another concept in magnetism.
The relationship between M and G is: M = 5/6 G
Magnetic dipole moment (P) is the product of pole strength and dipole length (P= m x 2l)
Magnetic dipole moment originates from the south pole and goes to the north pole.
A line joining the two poles is called the magnetic dipole axis.
The magnetic field intensity at a point P along the axis of a magnetic dipole is given by the equation (B).
