Solution:

It is stated in Faraday’s law of electromagnetic induction that whenever a conductor moves in an electromagnetic field, an electromagnetic field is induced across the conductor. If a close path is provided between the conductor and the ground, the induced emf causes current to flow in the system.

Allow for the placement of the conductor coil ABCD in a magnetic field. The magnetic flux will flow from the N pole to the S pole in the opposite direction. It is connected to the load through brushes that rest on the slip rings, and the coil is connected to it through slip rings.

Take, for example, Case 1 in the preceding illustration. Because the coil is rotating in the clockwise direction, the direction of induced current can be determined using Fleming’s right-hand rule, which indicates that it will be along the lines A-B-C-D.

Because the coil is rotating in a clockwise direction, the position of the coil will be the same as in the second case of the preceding figure after half of the time period. As a result, according to Fleming’s right-hand rule, the induced current will flow in the direction of the letter D, C, B, and A. As the graph illustrates, the current’s direction changes after half of the time period, indicating that we are receiving an alternating current.
