Across
  1. 3. a form of energy caused by the movement of electrons
  2. 5. an attractive force that acts between any two objects
  3. 7. a region around a charged object where the object’s electric force is exerted on other charged objects
  4. 10. energy caused by the movement of electrons
  5. 13. the force of attraction or repulsion of magnetic materials
  6. 14. the attraction or repulsion between magnetic poles
  7. 16. a force that one charge exerts on another – when the charges are the same sign, they repel; when the charges are opposite, they attract
  8. 17. a material that allows heat and electricity to pass through it
  9. 19. temporary magnet that loses its magnetism when the electric current is turned off
Down
  1. 1. a material or an object that does not easily allow heat, electricity, light, or sound to pass through it
  2. 2. to send out rays; to beam or shine
  3. 4. the region of space surrounding a body in which another body experiences a force of gravitational attraction
  4. 6. pole one of the two ends of a magnet where the magnetism seems to be concentrated
  5. 8. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
  6. 9. a machine that converts mechanical energy into electrical energy
  7. 11. to push away
  8. 12. to pull toward
  9. 15. an instrument for detecting and measuring small electric currents
  10. 18. a measure of the extra positive or negative particles that an object has
  11. 20. the region around a magnet where the magnetic force is exerted
