Alternating current generator (Dynamo)-AC Generator and Effective value of the alternating current

Alternating current generator is a device that converts mechanical energy into electric energy, When the coil rotates between the two poles of the magnet, it intercepts the magnetic flux lines which generate the induced...

Magnetic effect of the electric current and Magnetic flux density due to current in two parallel wires

In 1819, a Danish physicist (Hans Oersted) brought a small compass near a wire carrying an electric current and parallel to it, He noticed that the compass needle deflected and when he turned the...
