Across
  1. 4. an instrument used to measure force
  2. 5. an area of magnetic influence around a magnet
  3. 9. a tiny part of an atom that has a negative charge and moves around the nucleus
  4. 13. the flow of electricity through a conductor
  5. 16. a force acting between surfaces in contact. Friction acts to resist motion
  6. 17. a source of stored chemical energy
  7. 19. a fundamental force of nature that acts between charged particles and creates electric and magnetic fields
  8. 24. an object that sticks to iron
  9. 26. a material that prevents the flow of electricity, commonly plastic, rubber, glass, or air
  10. 27. a piece of iron that behaves like a magnet only when it is under the influence of an external magnetic field
  11. 28. a pathway for the flow of electricity
  12. 29. the interaction of electric and magnetic fields
Down
  1. 1. an attractive force between objects, like between Earth and objects on Earth
  2. 2. the material in a lightbulb (usually a thin wire) that makes light when heated by an electric current
  3. 3. to push away from each other
  4. 6. to pull toward each other
  5. 7. energy emitted as an electromagnetic wave
  6. 8. a material capable of transmitting energy, particularly in the forms of heat and electricity
  7. 10. energy of movement
  8. 11. the end of a magnet
  9. 12. the standard unit for measuring force in the metric system
  10. 14. the ability to apply force over a distance
  11. 15. the place on a component where connections are made to allow electricity to flow
  12. 18. an instrument that uses a free-rotating magnetic needle to show direction
  13. 20. energy that matter has because of its position
  14. 21. one item in a circuit
  15. 22. to act on and be acted upon by one or more objects
  16. 23. the process of turning iron into a temporary magnet
  17. 25. the movement of energy from one location to another
