# If the direction of electric current in a solenoid when viewed from a particular end is anticlockwise, then this end of solenoid will be:(a) west pole   (b) south pole   (c) north pole   (d) east pole

(c) north pole

Explanation

By applying the clock face rule, we came to the conclusion that, If the direction of electric current in a solenoid, when viewed from a particular end, is anticlockwise, then this end of the solenoid will be the north pole.

The clock face rule is used to determine the polarity of two faces of a current-carrying circular coil (solenoid) as well as an electromagnet.
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.
