Answer:

Barmagnet is permanent magnet. Electromagnet is a temporary magnet. An Electromagnet shows it's properties of magnetism only when current flows through it. Bar Magnet is permanent magnet. Actually, Bar Magnet is made by passing current through an iron/nickel/chromium bar but it retains the magnetic properties for a longer period of time, hence it becomes a permanent magnet. Electromagnets like Solenoids work only when current pass through them! By usage of properties such as electrical induction, Electromagnets can be used to magnetize other metallic objects.

Be sure to disconnect your electromagnet when it is not in use. Leaving the wires connected will drain your battery. The key difference between bar magnet and electromagnet is that the bar magnet has a permanent magnetic field whereas the electromagnet has a temporary magnetic field.
