Many devices may use of magnets and electromagnets. Audio speakers typically use a permanent magnet, and an electromagnet driven by the stereo amplifier, to attract and repel the speaker 'cone', thereby creating a disturbance in the air, known as sound. Video Cassette Recorders use magnets to encode the information onto the magnetic tape.
Hard disk drives also use magnets to encode information on the disk. Each bit of data is magnetized in one direction or the other, representing a 0 or 1.
Magnets are used in electric motors and generators, and the list could go on and on.

How are the uses of an electromagnet different from those of a permanent bar magnet?
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
