Across
  1. 1. A magnet made from a material that keeps its magnetism for a long time
  2. 3. A standard for measuring the thickness of a wire, where a lower gauge number indicates a thicker wire
  3. 6. The study of the behavior of electric charges, including how charge is transferred between objects
  4. 9. The transfer of charge without contact between materials
  5. 10. A coil of current-carrying wire that produces a magnetic field
  6. 13. Potential difference, the difference in electrical potential energy between two places in an electric field; measured in volts
  7. 15. The transfer of excess charge through a conductor to Earth

Down
  1. 2. A process by which an insulator or an insulated conductor receives a net charge.
  2. 4. Unit used to measure electric current
  3. 5. The opposition to the flow of electric charge
  4. 7. A magnet made from a material that easily loses its magnetism
  5. 8. An electric circuit with only one path through which charge can flow
  6. 11. The continuous flow of a charge, or electrons, in a complete circuit
  7. 12. A region that has a large number of atoms with aligned magnetic fields
  8. 14. The ends of a magnetic object, where the magnetic force is strongest.
  9. 16. The current in a circuit equals the voltage difference divided by the resistance; V=IR
  10. 18. A device that increases or decreases the voltage of alternating current (AC) circuits
