The direction of current in a solenoid is observed from one end. If the direction of current is anti-clockwise, the end of the solenoid acts as a north pole and vice-versa.

The correct option is A True
A current-carrying coil behaves like a thin disc magnet whose one face is north pole and the other face is south pole. The polarity of the two faces of the current carrying coil can be determined by using the clock face rule given below:
According to clock face rule, look at one face of the coil through which the current is passing:
1. If the current around the face of the coil flows in the clockwise direction, then that face of the coil is the south pole.
2. If the current around the face of the coil flows in the anticlockwise direction, then that face of the coil is the north pole.
Here, the direction of current in the coil is anti-clockwise, so this face of the coil will act like the north pole and the other face will act like the south pole. Thus, the given statement is true.
