In order to understand which metals are magnetic, it's helpful to review the five types of magnetism: 1. Diamagnetism: All matter is diamagnetic, which means it is weakly repelled by a magnetic field. In a magnetic material, the attraction to a magnet exceeds repulsion from diamagnetism. 2. Paramagnetism: A paramagnet…

So the common non-magnetic stainless steels have better corrosion resistance than the common magnetic grades because they have more chromium and molybdenum. In this photo, you can see that stainless steel is magnetic. For the technically minded, in the non-magnetic grades the atoms are lined up in a crystal structure known as austenite.

If nature is symmetrical, then perhaps a magnetic field can create a current. In 1831, some 12 years after the discovery that an electric current generates a magnetic field, English scientist Michael Faraday (1791–1862) and American scientist Joseph Henry (1797–1878) independently demonstrated that magnetic fields can produce currents.
