Dear student,

Hysteresis losses  occur when the armature rotates in a magnetic field.   The magnetic domains of the armature are held in alignment with the field in varying numbers, dependent upon field strength.   The magnetic domains rotate, with respect to the particles not held in alignment, by one complete turn during each rotation of the armature.   This rotation of magnetic domains in the iron causes friction and heat.  The heat produced by this friction is called magnetic hysteresis loss.
