Answer :

The magnetic field of a bar magnet is shown in the first figure. In which we can see inside the magnet the direction of the magnetic field is from the South Pole to the North Pole. But outside the magnet it is from North to the South Pole, it is because magnetic field always forms close loop.

A solenoid is a device which is formed when an insulated current-carrying wire is bent into a coil with N number of loops or turns. It is like the wrapping of a wire on a cylindrical object. The individual magnetic field of each turn contribute and it results in a magnetic field which is like the magnetic field of a bar magnet. The direction of the magnetic field inside the solenoid is determined by Right-hand thumb rule. That is, the magnetic field inside the solenoid is directed from south to north but outside the solenoid, it is from North to South, which are a similar magnetic field like a bar magnet.
