The north pole of a magnet is brought near to the current-carrying solenoid. State whether the north pole is attracted or repelled by the solenoid. Explain why.

The north and south pole of a solenoid depends on two factors. One, the direction of the current flow and two, the direction of the winding (clockwise or counter-clockwise). ... If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole.
