Question

state &explain clock face rule for determining polarities of current carring circular wire

Answer 1

This rule provides us a relation in the direction of current and magnetic field in the current carrying coil.

According to it, the current to be flowing in the anti-clockwise direction, then the face of the coil will behave like the North Pole. While if the current is in the clockwise direction, the face of the coil will behave like South Pole.

Answer 2

Answer:

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

(i) If the current around the face of the circular wire (or coil) flows in the clockwise direction, then that face of the circular wire will be South pole (S-pole).

(ii) If the current around the face of the circular wire (or coil) flows in the anti-clockwise direction, then that face of the circular wire will be North pole (N-pole).
