  1. 5. device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field
  2. 6. material that allows electrons to move easily through it
  3. 7. strong temporary magnet made by inserting an iron core into a wire coil and passing an electric current through the coil
  4. 9. device that contains a rotating electromagent that changes electrical energy to mechanical energy
  5. 10. 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
  6. 12. a force that affects subatomic particles and other objects that contain electrical charge
  7. 13. a piece of metal with a strong attraction to another metal object
  8. 15. material that does not allow electrons to move through it easily
  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 coiled wire with a charged current running through it
Down
  1. 1. property of some materials in which there is a force of repulsion or attraction between certain like and unlike poles
  2. 2. flow of charged particles, such as electrons or ions
  3. 3. electrical current is induced in a wire when it is moved through a magnetic field
  4. 4. opposotion to the flow of electrons through a conductor; measured in ohms
  5. 8. device that can increase or decrease the voltage of an alternating current
  6. 11. region around a magnet where magnetic forces act
  7. 14. unalike poles ________
