A permanent magnet in the shape of a thin cylinder of length 10 cm has Calculate the magnetization current IM.

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 (IM) 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
