Q. 12

# A permanent magnet in the shape of a thin cylinder of length 10 cm has Calculate the magnetization current I_{M}.

Answer :

Magnetization current equal to

Given:

The length of the cylinder is, the magnetic moment of the cylinder is

Formula used:

Magnetization current is the ratio between magnetic moment of the object and the length of the object, which is magnetized.

where

is the magnetization current, M is the magnetic moment and is the length of the object that is to be magnetized. has to be converted into meters

Explanation:

Magnetization current (I_{M}) is the current that flows in the primary winding of the transformer when no loads are attached to the secondary winding. This same current generates a magnetic field and energy is produced under no load condition.

Therefore, after solving the problem we get the value of the Magnetization current equal to
