How does 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
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.
If the north pole of a bar magnet is brought near the negative terminal of the battery, then the solenoid repels the bar magnet as like poles repel each other similarly the other end behaves as a south pole.

Answer:
A solenoid behaves like a bar magnet when a current is passed through it. Yes, the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. We can bring the North of a Bar Magnet towards one end of the solenoid. If the magnet is repelled, the end is north end of the solenoid .
