Question

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

Answer 1

Hi friend,

It is determined by the rule known as end rule.

End rule states that if the current is in anticlockwise direction the nearer end in north pole and the farther end is south pole
If it us in clockwise direction the near end corresponds to south pole and the further end corresponds to north pole.

Hope this helped you a little!!!
