प्रश्न
The back face of a circular loop of wire is found to be south magnetic pole. The direction of current in this face of the circular loop of wire will be:
(a) towards south
(b) clockwise
(c) anticlockwise
(d) towards north
उत्तर
clockwise
Because clockwise flow of current in a circular loop behaves like south pole.
