Question

What is solenoid ? How does a solenoid behave like a bar magnet

Answer 1

A solenoid is a long coil of circular loops of insulated copper wire.

# The magnetic field produced by a current carrying solenoid is similiar to the magnetic field produced by a bar magnet.

# One end of the current carrying solenoid acts like a magnetic north pole while the other acts like a south pole

# We can determine the north and south poles of a current carrying solenoid with the help of a bar magnet.This can be done as follows :
The north pole of a bar magnet is brought near to the both ends of a current carrying solenoid.The end of the solenoid which repels the north pole of bar magnet will ne its north pole and the end of the soleboid which will attract the north pole of the bar magnet will be its south pole.

Answer 2

A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a. Solenoid.
The field lines around a current -carrying solenoid is similar to that produced by a bar magnet. This means that a current -carrying solenoid behaves as having north pole and south pole.
