Product Details

Large Red/Green Alcino Bar Magnet

3.94" x 0.59" x 0.39"

This alnico bar magnet is ideal for magnetic demonstrations in classrooms or for use as a piece of equipment in the laboratory.  Alnico is an acronym referring to a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni) and cobalt (Co), hence al-ni-co. Alnico alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets. These alnico magnets are carefully painted red, for the north pole, and green, for the south pole.

The following is a list of types of magnets from strongest to weakest.

  1. Neodymium
  2. Hematite
  3. Ceramic
  4. Alnico
  5. Soft Iron
  6. Steel
