Across
  1. 4. The region around a magnet where magnetic forces act as a magnetic field.
  2. 6. energy an object has due to motion
  3. 7. An area surrounding an electron that exerts a force on anything nearby with an electric charge; strongest nearest the electron and weakens with distance.
  4. 9. when wire recoils becuase its magnetic field is repelling another magnetic field
  5. 12. when like charges or poles are close to eachother
  6. 15. a factory used to produce electricy from burning a fossil fuel or nuclear reaction
  7. 16. the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit.
  8. 18. A property of some materials in which there is a force of repulsion or attraction
  9. 20. The opposition to the flow of electrons through a conductor; measured in ohms.
  10. 21. a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons
  11. 23. the ability to create a current using a magnetic field while still being electrically isolated from the circuit
  12. 24. a metal used in electric circuits because it is a good conductor of electricity
  13. 26. An electrical circuit where the current has only one path. If the path is interrupted in any point, it stops current flow in the entire circuit.
  14. 28. A material that allows electrons to move easily through it.
  15. 29. a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons
  16. 30. An electrical circuit where the current flows through more than one path. If one path is interrupted, current will still flow through the other paths.
Down
  1. 1. the difference in electric potential between two points
  2. 2. transfer of energy using a force to move an object
  3. 3. a coil of wire with a current that acts a bar magnet.
  4. 5. A material that does not allow heat or electrons to move through it easily.
  5. 8. push or pull on an object
  6. 10. the branch of science that deals with electricity and magnetism
  7. 11. energy an object has due to its position(stored energy)
  8. 13. the relationship between electricity and magnetism.
  9. 14. A device that can increase or decrease the voltage of an alternating current.
  10. 17. A device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field.
  11. 19. a force produced when magnetic poles interact.
  12. 22. A device that contains a rotating electromagnet that changes electrical energy to mechanical energy.
  13. 25. total kinetic and potential energy of an object
  14. 27. soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
