Question

Give examples for natural and artificial magnets
What are temporary and permanent magnets?​

Answer 1

Answer:

1. An example of a natural magnet is the lodestone, also called magnetite. Other examples are pyrrhotite, ferrite, and columbite. Examples of permanent artificial magnets include refrigerator magnets and neodymium magnet.

2. A temporary magnet is a magnet that remains magnetized for only a small time interval as compared to a permanent magnet.

Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Permanent magnets are limited by the structure of the material.

Answer 2

A temporary magnet is a magnet that remains magnetized for only a small time interval as compared to a permanent magnet. The materials that are used to make temporary magnets are usually soft materials that have low magnetic properties such as annealed iron or steel.

magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets
