2. a force produced when magnetic poles interact
4. ferro magnet placed inside a coiled wire that can carry electricity
7. a type of fan that is kmaved by steam in a power plant to genrate electricty
11. A device that can increase or decrease the voltage of an alternating current.
13. energy that is in motion or transforming one type of energy to another
15. when opposite charges or poles are close they do this
16. 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.
17. Strong temporary magnet made by inserting an iron core into a wire coil and passing an electric current through the coil.
18. An electrical circuit where the current has only one path. If the path is interrupted in any point, it stops current flow in the entire circuit.
19. the physical interaction among electric charges, magnetic moments, and electromagnetic fields
20. a type of current that stays relativly constant voltage such as from a battery
24. The two ends of a piece of magnetic material where the magnetic forces are strongest, labeled north pole and south pole.
25. A material that allows electricity to move easily through it.

1. stored energy such as a battery or fuel that can be released to create motion
3. a flow of electricity through a wire or circuit.
5. A material that does not allow heat or electrons to move through it easily.
6. a factory used to produce electricity from burning a fossil fuel or nuclear reaction
8. when a wire recoils because its magnetic field is repelling another magnetic field
9. The region around a magnet where magnetic forces act. magnetic field.
10. a metal often used in electric circuits because it is a good conductor of electricity
12. rotating wire moves through a magnetic field producing current in the wire
14. a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons
21. an electric current experiencing force in a magnetic field and turning an axle
22. looped or coiled wire carrying a current
23. when like charges are close to each other they do this
