MAGNETS: Variety

MAGNETS: Variety

•  A large variety for use in the science laboratory including:
Alnico  |  Ceramic  |  Ferrite  |  Rubber  |  Haematite  |  Samarium   | Cobalt   | Bars   | C-Shape   | Cylindrical   | Discs  |  Horseshoe  |  Magnadur  |  Magnatoid  |  Oval   | Rare earth  |  Power  |  Pocket  |  Rectangular  |  Ring  |  Strip  |  U-Shape.

(Wikipedia excerpt: ..."A 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.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism...")
