Large 4" Red Silver Horseshoe Alnico Magnets

4 Inch Horseshoe Alnico Magnet
Painted With Keeper
This alnico magnet is carefully painted with the North and South poles marked.
Included is a steel keeper bar (not pictured) to protect the poles from damage or loss of magnetism.
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.
This horseshoe alnico 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 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. This alnico magnet is carefully painted with the North and South poles marked. Included is a steel keeper bar to protect the poles from damage or loss of magnetism.
