Across
- 3. the attraction or repulsion between magnetic poles
- 5. a device that changes mechanical energy into electrical energy.
- 7. The direct transfer of heat from one substance to another substance that it is touching.
- 11. A force that pulls objects toward each other
- 13. A type of magnet whose magnetic field is produced by the flow of electric current.
- 14. A force that opposes motion between two surfaces that are in contact
- 15. the space around a magnet where the force of a magnet can act
- 18. materials that transfer energy easily
Down
- 1. the weight is how much gravity pulls you down, and the mass is the amount of matter taking up space
- 2. the production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body.
- 4. the area surrounding an object in which another object could experience a force of gravitational attraction
- 6. the area around an electric charge that experiences the force exerted by the electric charge
- 8. Carries magnetic field, not current; Earth's core
- 9. A device that converts electrical energy to mechanical energy
- 10. A characteristic of those metals that are attracted to magnets and can be made into magnets; the ability to attract
- 12. two types exist-positive and negative
- 16. Do not allow electricity to flow through them easily
- 17. A form of energy caused by the movement of electrons.
