Question

How do you identify the polarity of an electromagnet ?​

Answer 1

Answer:

The polarity of the electromagnet is determined by the direction the current. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -).

Answer 2

• With the help of the second right-hand rule, the polarity of an electromagnet can be determined.
• These rule deals with the magnetic field, induced by current moving through a wire.
• To determine the polarity of an electromagnet, take the right hand, and wrap the fingers around the wire with the thumb points in the direction in which the current is flowing. now the fingers represent the direction of the lines of magnetic force.
