The bar magnet is a permanent magnet, whereas a solenoid is an electromagnet i.e., it acts as a magnet only when an electric current is passed through.
When a bar magnet is cut into two halves, both the pieces act as a magnet with the same magnetic properties, whereas when a solenoid is cut into two halves, it will have weaker fields.
The poles of the bar magnet are fixed, whereas, for a solenoid, the poles can be altered.
The strength of the magnetic field of a bar magnet is fixed, i.e., unaltered, whereas the strength of the magnetic field of a solenoid depends on the electric current that is passed through it.
Explanation:
Similarities between a Bar Magnet and a Solenoid
Bar magnet and solenoid both have attractive and directive properties, ie to align themselves along the external magnetic field.
The magnetic field at the axial point is the same for both.
