Across
  1. 3. a combination of invisible electric and magnetic fields of force
  2. 7. a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving
  3. 9. a substance which does not allow the passage of heat or sound
  4. 10. the south pole of a magnet
  5. 11. a property of an object that has more protons than electrons
  6. 14. A material that is both electrically conductive and magnetic
  7. 15. when you put two alike poles together, (North pole to North pole or South pole to South pole) they will repel each other
  8. 18. The magnetic field that protects Earth from cosmic radiation and from the charged particles emitted by our sun
  9. 20. one of the instruments for measuring electrical current par excellence
  10. 22. the area around a magnet in which the effect of magnetism is felt
Down
  1. 1. The force that pulls 2 magnets together when their opposite poles are facing each other
  2. 2. a form of radiation that travel through the universe
  3. 4. when an object has more electrons than protons, resulting in an excess of negative charge
  4. 5. radiant energy that travels in waves at the speed of light
  5. 6. the north pole of a magnet
  6. 8. theory The valence shell electron pair repulsion theory is a model used to predict 3D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion
  7. 12. points of Earth’s surface where the magnetic field is vertical, and the ends of a magnet where the magnetic field is strongest
  8. 13. If electrons are accelerated up and down the wires in the antenna, changing electric and magnetic fields will be produced in a similar manner to the electrons changing energy levels in atoms
  9. 16. generators use magnetism to produce electricity by moving a conductor through a magnetic field
  10. 17. phenomenon associated with magnetic fields, which arise from the motion of electric charges
  11. 19. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
  12. 21. The flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit
