Question

define clock face rule

Answer 1

hey dear-----------your answer is here:-

There are many rules in physics which are similar to clock rule, but the most common one is clock rule in Electromagnetisim.

Application: To find the pole of a current carrying loop.

If the current is flowing is clockwise direction then that side of loop behaves as south pole.

If the current is flowing is anit-clockwise direction then that side of loop behaves as north pole.

This rule is just another name given to right hand screw rule.

hope it helps :-)

Answer 2

According to the clock rule "When an observer, looking at the face of the coil, finds 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.
