Across
  1. 5. an electrical charge on an object that occurs when it has more protons than electrons
  2. 8. a combination of invisible electric and magnetic fields of force.
  3. 9. an electromechanical measuring instrument for electric current
  4. 10. the terminal of a battery that is connected to the positive plate
  5. 12. magnetic field an invisible force field that surrounds our planet, generated by the movement of molten iron in Earth's core, acting like a giant magnet and protecting the planet from harmful solar radiation and cosmic rays by deflecting them away
  6. 16. a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials
  7. 18. a disturbance in a magnetic and electric field that travels through space
  8. 19. phenomenon associated with magnetic fields
  9. 20. The property by which an ordinary piece of iron acquires magnetic properties temporarily due to the presence of another magnet close to it
  10. 22. region at each end of a magnet where the external magnetic field is strongest
Down
  1. 1. radiant energy that travels in waves at the speed of light
  2. 2. a force under the influence of which objects tend to move toward each other.
  3. 3. valence electron pairs surrounding an atom tend to repel each other. The greater the repulsion, the higher in energy (less stable) the molecule is
  4. 4. a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
  5. 6. to extend, spread, or move like rays or radii from a center
  6. 7. the state of an atom or object having more electrons than protons, resulting in an overall negative electrical charge
  7. 11. any atom or group of atoms that bears one or more positive or negative electrical charges
  8. 13. to force (something) to move away or apart
  9. 14. a generator is a device that converts motion based power or fuel based power into electric power
  10. 15. current a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space.
  11. 17. the pole of a magnet that points toward the south when the magnet is suspended freely
  12. 21. a material in which electric current does not flow freely
