Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
The most common magnetic material is steel, an alloy (mix) of iron, other metals, and carbon. Pure iron becomes magnetized in a magnetic field but does not stay magnetic. Steel can make a permanent magnet.agnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel.
