    They attract certain materials eg iron steel nickel cobalt. Magnetic materials are attracted to the poles of the magnet. On a bar magnet the poles are at either end of the magnet. Poles occur in pairs of equal strength. One pole - North seeking pole - N pole- pointing roughly to the Earth''s North pole. Other pole - South - S pole. Like poles repel

  • What materials Cannot be magnetized?

    2020-4-4 · Only select materials, like iron, cobalt, and nickel, can become magnetized in the presence of a magnetic field and remain so in the absence of that field. These are called ferromagnets. The human body can generate very weak or transient magnetic fields, however.

  • Why are Iron, Cobalt and Nickel Magnetic? | Physics Forums

     · However, if the material is ferromagnetic, once one introduces a mild external magnetic field, those dipoles line up and you get a strong magnetic field. Other materials have atoms which don''t tend to line their magnetic dipoles as much. Although, in a strong enough magnetic field, almost any material can become magnetic.
