Electric Potential Energy
... Negative charges flow from B to A. As they flow into the light, almost all of their potential energy is transformed to heat, which causes the filament to glow and give off light. ...

Electric and Magnetic Power - Everything You Need to Succeed 4th
... is called an electric field. Electric fields cannot be seen. Scientists show electric fields by drawing lines coming from an object. An electric field has the most strength when it is closest to a charged object. It loses strength as it gets farther away from the charged object. Negative electric fi ...

How transformers work
... Electromagnets differ from normal magnets in one major way! They are made by passing an electric current through a wire that has been wrapped around iron. The current creates a magnetic field and magnetises the iron core. When the current is turned off the iron loses its magnetism ...
