Answer 1

Explanation:

The difference between a permanent magnet and a temporary magnet is in their atomic structures.

• Permanent magnets have their atoms aligned all the time.
• Temporary magnets have their atoms aligned only while under the influence of a strong external magnetic field.

Answer 2

Explanation:

Permanent Magnets

Permanent magnets differ from temporary magnets by their ability to remain magnetized without the influence of a nearby external magnetic field. Typically, permanent magnets are made from "hard" magnetic materials where "hard" refers to a material's ability to become magnetized and remain magnetized. Steel is an example of a hard magnetic material.

Many permanent magnets are created by exposing the magnetic material to a very strong external magnetic field. Once the external magnetic field is removed, the treated magnetic material is now converted into a permanent magnet.

Temporary Magnets

Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.

One example of an industrial temporary magnet is an electromagnet used to move scrap metal in a salvage yard. An electric current flowing through a coil that surrounds an iron plate induces a magnetic field that magnetizes the plate. When the current flows, the plate picks up scrap metal. When the current stops, the plate releases the scrap metal.मार्च में अजब लैंग्वेज
