North/South Alnico Bar Magnets

Pack of 2 Red Blue Painted Magnets

2.95″ x 0.39″ x 0.24″

These Alnico bar magnets are 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 aluminum (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 with the North pole marked. 

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
