4. The space around a magnet where the magnetic force is exerted.
6. A device which changes electrical energy into mechanical energy.
9. This pole will attract the south pole of a magnet.
10. Region within a magnetic material in which the magnetization is in a uniform direction
11. What the Earth's core is made of.
12. A device which changes mechanical energy into electrical energy.

1. A magnetic field forms around a wire when this flows through the wire.
2. Elements that are strongly attracted to magnets.
3. A compass points to the southern magneticpole which is also known as this.
5. When an electric current is passed through a coil of wire wrapped around a metal core, a very strong magnetic field is produced.
7. A metal ring in an electric motor that reverses the current.
8. A system of train transportation that uses two sets of magnets
