| Question | Answer |
|---|---|
| electromagnet | a non-permament maget created by wrapping a wire around certain iron -bearing materials (nails) |
| magnetic poles | the stronger point of a magnet (usually north and south) |
| magnetic field | the lines of force extended from the poles of a magnet in a n arched pattern defining the area over which a magnetic force occours . |
| cricut | The path of an electric current |
| current electricty | continuos flow of electricty |
| closed cricut | ( like a closed brigde) allows electricty to flow ! |
| open cricut | ( like a open brigde) allows electricity to flow ! |
| conductors | an object that allows electrcity to pass through . examples of conductor = metal |
| insulaters | an object that DOES NOT allow electrcity to pass . Examples = Rubber, plastic, wood |
| parallel cricut | has more than one pathway.If one light goes out the other cricut stays on |
| series cricut | has only one path . if one light goes out , they all go out |
| atoms | Tiny materials within all objets within atoms are protons (= charge) electrons ( - charge) and neutrons ( no chare) |
| lightning | the static discharge between objects |
| michael Faraway | Invented The non-permanent Yet , powerful electromagnet |
| Ben franklin | Discoved lightning with a kite |
| Thomas Edison | Inventer of the lightbulb |
| like charge | repel |
