    How to Demagnetize a Magnet

    Alternating current rapidly switches directions changing the orientation of the electromagnetic field. The magnetic dipoles try to orient according to the field but since it s changing they end up randomized. The core of the material may retain a slight magnetic field due to hysteresis.

    Magnetic fields are generated by electric currents. Alternating curents will produce alternating magnetic fields so the waveform of the current really only tells you how the field strength of the magnetic field will vary with time it says nothing about rotation with more information. There are several different types of motors.

    An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity most alternators use a rotating magnetic field with a stationary armature. Occasionally a linear alternator or a rotating armature with a stationary magnetic field is used. In principle any AC electrical generator can be called

    What is Rotating Magnetic Field. In the last tutorial of the induced torque in the loop we have discussed that if there are two fields in any electrical machine then torque will be produced by the linking of these two fields.This torque has the ability to line-up these 2 fields. If one field is existing at the stating part of AC machines and the other is at the rotor of the machine then these
