Compasses
Its called a compass and it always points in the direction of north so you can easily determine your relative direction to the north.
A compass is a device that uses a magnetic needle to show you which way is north, helping you navigate and find your way when you are lost.
A generator is a machine that uses a magnet to produce electricity. As the magnet rotates within coils of wire, it induces an electric current to flow, generating electrical power.
A bar magnet, like other magnets, has uses based on its magnetic attraction. This magnetic attraction draws other ferromagnetic materials to it or the bar magnet towards them. These uses include: picking up small ferromagnetic items such as screws and metal shavings; being used as "magnetic stirring rods" on laboratory hotplates; and holding papers and other items to the sides of refrigerators. Like other magnets, the magnetic field generated by a bar magnet can damage electronic equipment. A bar magnet placed near a hard drive, computer disk, or even a video cassette can cause the data stored by the magnetic particles on the item to be damaged. Bar magnets placed on the sides of speakers or other sound devices can cause disruptions in the sound or even permanent damage. A bar magnet placed on the side of a computer can result in the system being deactivated, and may even make it completely inoperable.
Permanent magnets are used in food processing to remove metal fragments resulting from the manufacturing process. Magnets are also used in recycling centers to separate iron. A magnetic resonance imaging machine uses a magnet.

an magnet is a object that attracts or repel
Electromagnets are used for a wide variety of uses like in motors to regulate the speed of motor and used in cranes to lift heavy metal objects and they can used in electronic devices
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.

An electric motor uses electricity to create a magnetic field which interacts with a permanent magnet to produce motion. This motion can be harnessed to do mechanical work in devices like fans, pumps, and vehicles.
