Across
  1. 1. produces a Voltage or EMF
  2. 6. This motion can take many forms. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital.
  3. 7. known as the geomagnetic field
  4. 10. a type of electromagnetic radiation that includes electric and magnetic fields that oscillate and travel as waves.
  5. 14. a cation
  6. 15. a material that allows electricity to flow through it easily
  7. 17. the relationship existing between things or persons that are naturally or involuntarily drawn together.
  8. 19. the state of having a surplus of electrons
  9. 20. excitation field is provided by a permanent magnet instead of a coil.
  10. 21. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  11. 22. An electrical material in which electric current does not flow freely.
Down
  1. 2. points toward the south when the magnet is suspended freely
  2. 3. opposite poles attract while like poles repel.
  3. 4. radiant energy that travels in waves at the speed of light.
  4. 5. When you try to place two like poles together (north to north or south to south), they will repel each other.
  5. 8. a form of radiation that travels throughout the universe.
  6. 9. a combination of invisible electric and magnetic fields of force.
  7. 11. a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
  8. 12. the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit.
  9. 13. the region where the external magnetic field is the strongest at each end of a magnet.
  10. 16. a north-seeking pole of a magnet.
  11. 18. is one of the instruments for measuring electrical current par excellence.
