| Question | Answer |
|---|---|
| Static Electricty | the build up of electric charges that stay on an object |
| Electric Charge | parts of matter that are described as positive or negative charges |
| Electric Current | the flow of electric charges |
| Series Circuit | a circuit with one path of current. |
| Parallel Circuit | a circuit with more than one path of current |
| Magnetic Field | the space around a magnet in which magnetic forces operate |
| Electromagnet | a temporary magnetic field made of coiled wire which electric current passes through |
