Q: What causes iron, nickel, and cobalt to be attracted to ...

Physicist: The magnetic properties of a material are governed entirely by the configuration of the electrons in that material. In metals there are two types of electrons: bound electrons and free electrons. The free electrons are free to move between atoms, and are the cause of conductivity in

Classes of Magnetic Materials Institute for Rock Magnetism

When you think of magnetic materials, you probably think of iron, nickel or magnetite. Unlike paramagnetic materials, the atomic moments in these materials exhibit very strong interactions. These interactions are produced by electronic exchange forces and result in a parallel or antiparallel alignment of atomic moments. Exchange forces are very large, equivalent to a field on the order of 1000 ...

Magnetite Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
