| A | B |
|---|
| static electricity | positive and negative charges are no longer equal |
| repels | positive to positive; negative to negative |
| copper | good conductor used in electric flow |
| poles | magnetic field is strongest here |
| insulator | stops electric current to flow |
| electromagnet | gets stronger the more turns of the metal coil |
| Michael Faraday | discovered electric current and shared his discovery with other scientists |
| electrical energy | spinning coiled wire around a magnet |
| lightning | releasing negative particles toward positive particles on the ground or between clouds |
| insulators | wood, rubber, plastic |
| series circuit | single path; one light is out - they all go out |
| parellel circuit | pair of paths; one light out - the others will stay lit |
| compass needle | points the Earth's magnetic north-south poles |
| electric current | charge in motion |
| magnetism | the pushing or pulling force that exists when a magnetic material is near |
| resistance | opposes the flow of electric current through a material |
| magnetic field | invisible field that goes out in all directions |
| electromagnet | can be turned off and on; not like a natural magnet |
| parallel circuit | house is wired this way; allows appliances to use different amounts of electric current |
| insulators | electrons have a much more difficult time moving from atom to atom |
| copper wire | electrons can move easily from atom to atom |
