Across
- 6. The region around a magnet or current-carrying wire where magnetic forces act.
- 7. A material that allows electric current to flow easily.
- 8. A temporary magnet created when electric current flows through a coil of wire around an iron core.
- 9. A method used to determine the direction of a magnetic field around a current-carrying conductor.
- 10. The opposition to the flow of electric current in a circuit.
- 12. The rate of flow of electric charge through a conductor, measured in amperes (A).
- 15. A material that resists the flow of electric current.
- 16. The difference in electrical energy between two points in a circuit, measured in volts (V).

Down
- 1. A magnet that produces a constant magnetic field without needing electricity.
- 2. A circuit with only one path for current to flow.
- 3. A circuit with more than one path for current to flow.
- 4. A wire wound into loops that strengthens the magnetic field when current flows through it.
- 5. A closed path that allows electric current to flow.
- 11. Two or more cells connected together to provide greater voltage.
- 13. A single source of electrical energy that converts chemical energy into electrical energy.
- 14. Energy produced by the movement of electrons.
