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