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 |
