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