Physics is an interesting subject for some people. It covers wide arrays of topics. One of them is magnetism. It is included as a physical phenomenon. The ferromagnetic materials can be used to produce magnetic fields and turn into a permanent magnet. The prevalent ferromagnetic materials include cobalt, nickel, iron and their alloys. If you are curious to find out more facts about magnetism, check the following post:

Facts about Magnetism 1: the first observance of magnetic

Lodestone was considered as the first object observed with permanent magnetism. It contained Fe3O4 or magnetite.

Facts about Magnetism 2: the effects of magnetism

Most effects of magnetism spotted in our daily life are always associated with ferromagnetism. Actually, other types of magnets and a magnetic field also produce the effects.

Facts about Magnetism 3: the relationship with magnetic field

The complex relationship is spotted on the antiferromagentic materials and magnetic field. Spin glasses and chromium are the antiferromagentis materials. The weakly repelled materials include diamagnetic materials like carbon and copper. Oxygen and aluminum are included as paramagnetic materials, which have weak attraction to a magnetic field.

Facts about Magnetism 4: laboratory instruments

The laboratory instruments will be used to detect the force of a magnet toward the antiferromagentic, diamagnetic and paramagnetic materials. All of them usually are included as non-magnetic materials in our daily life.
