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.

Solenoid:
A solenoid is a long coil that contains a large number of close turns of insulated copper wire. When a power source is connected to both its ends then it behaves like a magnet bar.

The behavior of a solenoid is like a magnet bar:
Let us see the diagram below that represents a solenoid.  Both ends of a coil containing a large number of close turns of insulated copper wire are connected to a battery B through a switch X. When a current is passed through it, it behaves like a magnet bar and a magnetic field can be experienced around it.


Determination of north and south poles of a current–carrying solenoid with the help of a bar magnet-
The magnetic field pattern of a current-carrying solenoid resembles that of a bar magnet. One end of a solenoid behaves like a north magnetic pole and another one behaves like a south magnetic pole as shown in the figure below.
