Across
- 2. more protons than electrons
- 4. a region around a charged object where the object's electric force is exerted on other charged objects
- 5. a machine that converts mechanical energy into electrical energy
- 6. a force that one charge exerts on another – when the charges are the same sign, they repel - when the charges are opposite, they attract
- 11. an attractive force that acts between any two objects
- 12. the region of space surrounding a body in which another body experiences a force of gravitational attraction
- 14. an instrument for detecting and measuring small electric currents
- 15. energy caused by the movement of electrons
- 17. to pull toward
- 19. a state where an object or particle has an excess of electrons compared to protons
- 21. the force of attraction or repulsion of magnetic materials
- 22. one of the two ends of a magnet where the magnetism seems to be concentrated
- 24. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
- 25. to send out rays; to beam or shine
- 26. a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space
Down
- 1. the south-seeking pole of a magnet
- 3. the attraction or repulsion between magnetic poles
- 7. a material or an object that does not easily allow heat, electricity, light, or sound to pass through it
- 8. a form of energy caused by the movement of electrons
- 9. temporary magnet that loses its magnetism when the electric current is turned off
- 10. to push away
- 13. the region around a magnet where the magnetic force is exerted
- 16. a measure of the extra positive or negative particles that an object has
- 18. a material that allows heat and electricity to pass through it
- 20. a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
- 23. a north-seeking pole of a magnet
