Question

The direction of current flowing in the coil of an electromagnet at its two ends X and Y are as shown below:

(a) What is the polarity of end X?
(b) What is the polarity of end Y?
(c) Name and state the rule which you have used to determine the polarities.

Open in App

Solution

(a) The polarity of end X is south because current is flowing in clockwise direction at this end.
(b) The polarity of end Y is north because current is flowing in anticlockwise direction at this end.
(c) We have used clock face rule to determine the polarities.
