How docs a solenoid behave like a magnet ? Can you determine the north and south poles of a current-carrying solenoid with the help of a bar magnet? Explain.
Answers
Answer:
Solenoid behaves like a magnet as it has a soft iron core with insulated copper wire over it. When a current is passed through the solenoid, magnetic field is produced around it. The magnetic field produced is similar to the magnetic field of a bar magnet. Field lines produced by solenoid are shown in the attached diagram.

Explanation:
A current carrying solenoid behaves like a bar magnet and the polarities of its ends depend upon the direction of current flowing through it . In order to determine the polarities of its ends , place it in a brass hook and suspend it with a long thread so that it moves freely . Bring north pole of a bar magnet near one of its end . In case the solenoid move towards the bar magnet , that end of the solenoid is a South pole and in case the solenoid moves away from the magnet , that end of the solenoid is its north pole . similarly, we can determine the polarity the other end of the solenoid .
