E&M review

6. the relationship between electricity and magnetism.
11. A device that can increase or decrease the voltage of an alternating current.
12. The opposition to the flow of electrons through a conductor;
14. An electrical circuit where the current has only one path. If the
16. A device that contains a rotating electromagnet that changes electrical energy to mechanical energy.
17. Strong temporary magnet made by inserting an iron core into a wire coil and passing an electric current through the coil.

1. A material that allows electrons to move easily through it.
2. A property of some materials in which there is a force of repulsion or attraction between certain like and unlike poles.
3. is interrupted in any point, it stops current flow in the entire circuit.
4. A device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field.
5. An electrical circuit where the current flows through more than one path. If one path is interrupted, current will still flow through the other paths.
7. The region around a magnet where magnetic forces act.
8. a force produced when magnetic poles interact.
9. in ohms.
10. The two ends of a piece of magnetic material where the magnetic forces are strongest, labeled north pole and south pole.
13. a coil of wire with a current that acts a bar magnet.
15. A material that does not allow heat or electrons to move through it
