What is the unit of susceptibility?
In electromagnetism the magnetic susceptibility (Latin: susceptibilis, “receptive”; denoted X) is a measure of how much a material will become magnetized in an applied magnetic field. Mathematically, it is the ratio of magnetization M(magnetic moment per unit volume) to the applied magnetizing field intensity H.
The magnetic induction left behind in the sample after the magnetizing field has been removed is called
Declination is the angle between:
The ferromagnetic materials can be magnetised easily because
What kinds of materials are used for coating magnetic tapes?
A particle of charge q and mass m moves in a circular orbit of radius r with angular speed. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on
To find the magnetic moment due to a single particle, it is advisable to consider the equivalent current due to it
A wire of length L m carrying current i A is bent in the form of a circle. The magnitude of magnetic moment is
If r is the radius of the circle,
then L=2πr or, r=L/2π
