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