Can Any Metal Become Magnetized?
Magnetite is a brownish-black mineral that is strongly magnetic and found in nature. It is found in many types of rocks and is a very important source of iron.
- Rubbing magnetite (or another magnetic material) against a non-magnetic metal can cause it to become magnetic!
