The direction your thumb is pointing is the direction of the. The direction of the current follows the. You can determine the polarity of a solenoid by using Clock Rule.

Polarity of an electromagnet. Look at the face of loop if the current around that face is in anticlockwise direction the face has the north polarity while if the current at that fave is in clockwise direction the face has the South polarity. There are some simple rules to help you find out which end of an electromagnet is north and which is south.

2Current passing through a conductor is increased from 10 A to 15 A. Answer 1 of 7. How can the polarity of an electromagnet be determined if the direction of current flow is known.

How can the polarity of an electromagnet be determined if the direction of current flow is known. This decreases the strength of the magnetic field produced by the conductor. When using electromagnets pay attention to the fact that there is both a positive and a negative side with electrons going from minus to plus.

Current flow is from positive to negative. If the current is flowing in anti-clockwise direction then the face of the loop shows North Pole. Confusingly in the convention current travels from positive to negative.
