Across
- 3. to send out rays; to beam or shine, electromagnetic wave, a wave that consists of oscillating electric and magnetic fields, which radiate outward
- 7. a form of energy caused by the movement of electrons, magnetism ,the force of attraction or repulsion of magnetic materials
- 10. a material that allows heat and electricity to pass through it, electromagnet, temporary magnet that loses its magnetism when the electric current is turned off
- 11. insulator, a material or an object that does not easily allow heat, electricity, light, or sound to
- 14. force, an attractive force that acts between any two objects, attract, to pull toward
Down
- 1. force, the attraction or repulsion between magnetic poles, electrical force, a force that one charge exerts on another – when the charges are the same sign, they
- 2. to push away, magnetic field, the region around a magnet where the magnetic force is exerted
- 4. - when the charges are opposite, they attract
- 5. a machine that converts mechanical energy into electrical energy, electrical energy, energy caused by the movement of electrons
- 6. the speed of light
- 8. an atom or molecule with a net electric charge due to the loss or gain of one or more
- 9. or space, positive charge, more protons than electrons
- 11. current, a flow of charged particles, such as electrons or ions, moving through an electrical
- 12. pole, one of the two ends of a magnet where the magnetism seems to be concentrated, galvanometer, an instrument for detecting and measuring small electric currents
