What causes magnetism?. How is magnetism linked to electric charges?. Magnetic fields come from . moving. . charges. . a moving charge around an atom produces a magnetic field. currents in wires will produce magnetic fields. Surrounding every magnet is area where they are able to exert a force on “ferromagnetic” objects.. *A ferromagnetic material is one that is both attracted to a magnet, and can become magnetized such as iron, nickel or cobalt.. g. eraint.lewis@sydney.edu.au.
