The direction of current in the coil at one end of an electromagnet is clockwise. This end of the electromagnet will be:(a) north pole   (b) east pole   (c) south pole   (d) west pole

By applying the clock face rule, we came to the conclusion that, if the direction of current in the coil at one end of an electromagnet is clockwise, then this end of the electromagnet will be the south pole, because the clockwise flow of current induces south polarity.

According to this rule, if we look at one face of the circular wire (or coil) through which a current is passing, we have the following conclusions:

1. If the current around the front face of the circular wire (or coil) flows in the Clockwise direction, then this face of the circular wire will be the South pole (S-pole).

And, the flow of current in the back face of the circular wire will be Anticlockwise and acts as a North pole.

2. If the current around the front face of the circular wire (or coil) flows in the Anticlockwise direction, then this face of the circular wire will be the North pole (N-pole).

And, the flow of current in the back face of the circular wire will be Clockwise and acts as a South pole.
