Magnetic ball mill. Similar in construction with a magnetic stirrer, this can be done by adding small beads made of magnetic materials, such as steel, nickel or magnetic stainless steel in a large strong lidded container. Beneath the container, a magnet glued to an electric motor rotates, which causes the beads to spin.

5. MAGNETISM Magnetism brings to mind horseshoe magnets and iron filings. However, magnetism is very closely related to electricity. In 1819 the Danish physicist and chemist, Hans Christian Oersted (), during a lecture demonstration, observed that an electric current can affect a magnetic compass needle * and thus united what until then had been viewed as two distinct subjects[1].
