Current flows through the solenoid from X to Y as shown. Using the right-hand grip rule, which end of the solenoid becomes the north pole?
Answer Details
To determine which end of the solenoid is the north pole, use the right-hand grip rule for a solenoid: wrap the fingers of your right hand around the solenoid in the direction the conventional current flows around the coils. Your thumb then points toward the north pole.
With current flowing from X to Y through the solenoid, applying the right-hand grip rule shows that end X becomes the north pole.
Alternatively, looking at the solenoid from end X, if the current flows anticlockwise, that end is a north pole (think: N for aNticlockwise). If the current flows clockwise, that end is a south pole.
