The 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, a magnetic field is produced around it. The magnetic field produced is similar to the magnetic field of a bar magnet.

the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. If the magnet is repelled, the end is north end of the solenoid. If the magnet is attracted, the end is south end of the solenoid.

Answer:

If a conducting wire is wound in form of a cylindrical coil whose diameter is less in comparison to its length, the coil is called a solenoid.

The magnetic field lines of a current carrying solenoid are similar to the magnetic field lines of a bar magnet. Thus a current carrying solenoid behaves just like a bar magnet

The north and south pole of a current carrying solenoid can be determined by the help of a barmagnet. If the magnet is repelled the end of the solenoid will be North and if the magnet is attracted it is the south pole of the solenoid
