Solution

The correct option is C

north


Clock face rule

  • By the clock face rule, if the current seems to be flowing in the clockwise direction, the respective coil is the south pole.
  • If the current seems to flow in the anticlockwise direction, the respective face of the solenoid is the north pole.

Answer:

Thus, the correct option is (C) “North”.
