What is a ceramic magnet?Ceramic magnets (also known as ferrite magnets) were developed in the 1960's as a low cost alternative to metallic magnets. They are composed of iron oxide and strontium carbonate. While their hard, brittle quality and low energy exclude them from some applications, ceramic magnets have won wide acceptance due to their corrosion and demagnetization

Magnetism - Simple English Wikipedia, the free encyclopedia

Magnets. Magnetism can be made by a permanent magnet, or by electricity in a wire. This is called an electromagnet. When magnets are put near magnetic objects, the magnet and the object are pulled toward each other. This is called magnetic attraction. Magnets can also repel (push away) other magnets.

Magnets And Magnetism For Kids With Pictures & Examples

Nov 02, 2015 · Permanent Magnets. After being 'magnetized' (made into magnets), some ferromagnetic materials don't lose their magnetic power. This is the property of being magnetically 'hard'. Other materials are magnetically 'soft', and do not retain their magnetism. Magnets that keep their magnetism are known as 'permanent magnets'.

Magnet - Simple English Wikipedia, the free encyclopedia

A magnet is a very special metal. When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer. Also, if the two poles are the same, the two magnets will push away, or repel, from each other.
