Magnetism Mastery Quiz

Electric currents and magnetic moments of elementary particles give rise to a magnetic field, making magnetism one of two aspects of electromagnetism.

Ferromagnetic materials, such as iron, cobalt, nickel, and their alloys, are strongly attracted by magnetic fields and can be magnetized to become permanent magnets.

Neodymium and samarium are examples of rare-earth metals that exhibit ferromagnetism.
