Magnets & Magnetism

1. A north and south pole will do this.
3. Electromagnet are created when an electrical ______ run through a coil of wire.
7. A simple rule that helps determine the direction of a magnetic field.
11. The strongest magnets commercially available and are incredibly resistant to demagnetization.
13. Two north poles will do this.
15. A kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements.
17. Creates a magnetic field by moving an electrical current through a coil.
18. The reduction or complete removal of magnetic properties from a magnet.

2. Only creates a magnetic field if exposed to a permanent magnetic field or an electrical current.
4. A magnet that occurs naturally in nature.
5. The class of physical attributes that occur through a magnetic field; allow object to repel and attract.
6. Magnets which are made from magnetizing different materials and made in different shapes and sizes.
8. Naturally magnetized pieces of the mineral magnetite.
9. A materiel or object that generates a magnetic field.
10. An object made from magnetized material that creates a persistent magnetic field.
11. The region of a magnet that the magnetic field originates.
12. The region around a magnetic material or a moving electrical charge within the force of magnetism acts.
14. The region where the external magnetic field is the strongest at each end of a magnet.
15. A liquid that is attracted to the poles of a magnet.
16. The region of a magnet that the magnetic field ends.
