Man-Made Magnets Man-made magnets used in automotive applications today are typically made from an Aluminum, Nickel, and Cobalt (AlNiCo) compound and then magnetized in a machine that produces a strong electromagnetic field. This material can be configured in a manner that can allow multiple magnetic pole and axis configurations to meet the custom needs of automotive electrical components. These types of magnets are known as Permanent Magnets. This is because they are always magnetic, always ready to be used, and they don't loose their magnetic strength as rapidly as polarized iron. Magnets have a magnetic field that exists around them. The magnetic field strength is very strong right next to the magnet and gets weaker further away from the magnet. The effect of a magnetic field can be seen by placing small iron filings around a magnet as shown below. The filings line up with the magnetic field. Magnetic fields are weaker in air and stronger when it can exist in a ferrous material like iron.
