Electricity and magnetism
Across
- 3. motor-device that contains a rotating electromagent that changes electrical energy to mechanical energy
- 4. strong magnet producing electric charges
- 7. region around magnets where magnet forces act
- 8. two end of a magnet
- 9. material that allows electrons to move easily through it
- 11. an electric circuit where the current has only one path; if the path is interrupted at any point, it stops current flow in the entire circuit
- 12. material that attracts and repels
- 15. opposotion to the flow of electrons through a conductor; measured in ohms
- 16. an electric circuit where the current flows through more than one path; if one path is interrupted, current will still flow through the other parts
- 17. a coil of wire with a current that acts as a bar magnet
Down
- 1. device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field
- 2. the relationship between electricity and magnetism
- 5. the force that brings magnets together in electricity
- 6. force produced when poles interact
- 10. device that can increase or decrease the voltage of an alternating current
- 13. flow of charged particles, such as electrons or ions
- 14. material that does not allow electrons to move through it easily
