Across
- 3. this is one of the two ends of a magnet where the magnetism seems to be concentrated
- 4. this is the action of sending out rays/shining
- 7. this is the action of an object having more protons than electrons
- 11. this is a measure of extra positive or negative particles that an object has
- 13. this is the action of pushing away
- 15. the action of pulling towards
- 16. this is the force of attraction or repulsion of magnetic materials
- 18. these are atoms or molecules that have a net charge due to having lost or gained at least one electron
- 19. this is a material or object that does not easily allow heat, electricity, light, or sound pass through it
- 20. this is energy caused by the movement of electrons
Down
- 1. this is the south seeking pole of a magnet
- 2. this is a form of energy that is caused by the movement of electrons
- 5. this is the north-seeking end of a magnet
- 6. this is a machine that measures and detects small electrical currents
- 8. this is a machine that turns mechanical energy into physical energy
- 9. this is the region of space around a body where another body experiences a force of gravitational attractions
- 10. this is the flow of charged particles, such as electrons or ions, moving through an electrical conductor or space
- 11. this is a material that allows heat and electricity to pass through it
- 12. this is a temporary magnet that looses it's magnetism when the electric current is turned off
- 14. this is a state where an object has an excess of electrons compared to it's protons
- 17. this is the attraction between magnetic poles
