A bar magnet is a rectangular object that has a magnetic field. ... A type of magnet in which the magnetic field is produced by the flow of electric current. An electromagnet works on the principle that an electric current not only allows electrons to flow in a circuit, but also generates a small magneticfield.

hey... There!
♥️♥️There is no such thing as a bar magnet whose magnetic moment is due to electric currents alone. A bar magnet is composed of a ferromagnetic material such as iron and its magnetism is mainly due to electron spins (spin is a fundamental quantum property and there is no evidence that it involves any actual motion).♥️♥️♥️
hope it helps you
