Across
  1. 3. anything that has mass and takes up space
  2. 4. external force given off by a magnet; strongest at the poles
  3. 8. a circuit component that slows or limits the flow of electric current
  4. 10. Field area surrounding charged particles/objects within which a force can be exerted on other charged particles/objects
  5. 12. the sudden flow of electric charge between two charged objects, due to a buildup of static electricity
  6. 17. temporary magnet made by placing a piece of iron inside a current carrying coil of wire
  7. 20. piece of metal that bends when overheated to open the circuit and prevent current from flowing
  8. 21. device that uses an electromagnet to convert electrical energy into mechanical energy
  9. 23. small piece of metal within that melts when overheated to open the circuit and prevent current from flowing
  10. 24. a closed path an electric current flows through
  11. 27. neutrally charged particle
Down
  1. 1. a charge imbalance that results in the buildup of excess electric charge on an object
  2. 2. a device that converts chemical energy to electrical energy
  3. 5. the simplest form of matter
  4. 6. tool used to detect the presence and magnitude of an electric charge
  5. 7. the push (force) that causes charge to move
  6. 9. negatively charged particle
  7. 11. restrict the flow of electrons
  8. 13. a material that gives off an external magnetic field, making it possible to apply a force over a distance
  9. 14. positively charged particle
  10. 15. the tendency of a material to oppose the flow of electrons through it
  11. 16. device that uses an electromagnet to convert mechanical energy into electrical energy
  12. 18. property of some materials that allows them to give off an attractive or repulsive force
  13. 19. the net movement of electric charge in a single direction
  14. 22. the amount of current is directly proportional to the voltage difference
  15. 23. phenomenon where objects placed in a strong magnetic field become magnetized due to the poles within their atoms aligning
  16. 25. allow the flow of electrons
  17. 26. process of removing excess charge on an object by transferring e- to another object to neutralize the electrical imbalance
