Name and state the rule by which the polarity at the ends of a current carrying solenoid is determined.

Solution:

The right hand thumb rule is the name of the rule. It asserts that if the current-carrying conductor is held in the right hand with the thumb pointing in the direction of current flow, the fingers will encircle the wire in the direction of magnetic field lines.
