Use of Temporary magnet

Temporary magnets are prepared from soft metals, and only preserve their magnetism while close to a permanent magnetic field or electronic current. These magnets are those which work like a permanent magnet when they are surrounded by a strong magnetic field, but lose their magnetism when the magnetic field disappears. Common temporary magnets include nails and paperclips, which can be picked up or moved by a strong magnet. Examples would be paperclips and nails and other soft iron items.

The soft magnet is prepared by magnetic materials made by an alloy of cast iron and nickel. It is a temporary magnet. This type of material, when placed in a magnetic field, becomes a magnet. As soon as the magnetic field is removed magnetism disappears. In motors, generators, transformers etc. this type of magnet is used. Besides, for the manufacture of the electromagnetic bell of different shape, for a crane to lift different heavy materials this type of magnet is used. In addition, for manufacturing ear pitch of telephone and electromagnet lock at the door this magnet is used. A temporary magnet can also be created by using an electrical field.
