Answer:

The correct option is c) north pole

Explanation:

Using the clock face rule, we found that if the flow of electric current in a solenoid is anticlockwise, that end is the north pole.

Both a current-carrying circular coil (solenoid) and an electromagnet use the clock face rule to identify their polarity.
By looking at one face of the circular wire (or coil), we can deduce the following:

1. The front face of the circular wire (or coil) is the South pole if the current flows clockwise around it (S-pole).
The current flow in the circular wire is anticlockwise and works as a North pole.

2. The front face of the circular wire (or coil) is the North pole if the current travels anticlockwise around it (N-pole).
The current flow in the circular wire is clockwise and functions as a South pole.
