Free-hanging magnet. Bar magnet suspended on a string,aligning itself with the Earth's magnetic field (itself caused by the Earth's iron core). Magnets are made of metals like iron. The freedom of movement of electrons within the metal,and the alignment of the electrons,is what causes the phenomenon of magnetism | |
