Dear student,

The bar magnet is what is termed a permanent magnet . This means that it is "always on" and can be used to do things like pick up paper clips. The electromagnet is created by winding a coil of wire about a ferromagnetic core and running a direct current through that coil. Only when the current is flowing will the electromagnet be operating. With the current switched off, the magnetic field around the coil of wire disappears, and the power of the electromagnetic disappears as well.
