Across
  1. 1. an instrument that uses a freely moving magnetic needle to indicate direction.
  2. 4. energy that an object has because of its motion or its position
  3. 5. the energy an object has while in motion
  4. 8. a type of magnet in which the magnetic field is produced by an electric current. (usually contains a wire wound into a coil).
  5. 10. the energy an object stores while at rest
  6. 13. a material electrons/energy do not moves easily through
  7. 14. any material capable of attracting iron and producing a magnetic field.
  8. 15. a device that transforms mechanical energy into electrical energy.
  9. 17. a conductive loop that allows charged particles to continually move through it.
  10. 18. the ability to do work or cause change; the ability to move an object some distance
  11. 20. energy stored as a result of applying a force to deform an elastic object.
  12. 21. a conductive loop with an opening which does allow the particles to move
  13. 22. energy in the form of charged particles
Down
  1. 1. energy that is stored in the bonds between atoms
  2. 2. the energy an object has as a result of its location above the earth’s surface
  3. 3. energy that does not need matter to travel; light; sun (solar)
  4. 6. either of two opposing forces or parts, such as the poles of a magnet (n & s).
  5. 7. energy in the form of heat
  6. 9. a material electrons/energy moves easily through
  7. 11. an invisible field around a magnet.
  8. 12. a property of certain kinds of materials that causes them to attract iron or steel.
  9. 16. to push away, as similar poles of two magnets push away from one another.
  10. 18. current the number of electrons that pass a given point in a certain amount of time - ampere (a)
  11. 19. a conductive loop with an opening which doesn’t allow the particles to move
