| Term | Definition |
|---|---|
| electric charge | a property leading to electromagnetic interactions between matter particles |
| static electricity | buildup of electric charge on an object |
| electric conductor | material through which charges move freely |
| electric insulator | material through which charges cannot move freely |
| semi conductor | material through which charges move more free than an insulator , but less than a conductor |
| electric current | rate of flow of electric charges |
| voltage | amount of work required to move a charge between two points |
| resistance | opposition to the flow of freely moving electric charges |
| electric circuit | a complete, closed path through which electric charges can flow |
| series circuit | all parts are connected in a row that forms one path for the electric charges to follow |
| parallel circuit | charges have more than one path to follow |
| magnet | any material that attracts iron or objects made of iron |
| magnetic force | a push or pull |
| magnetic pole | a magnets two ends |
| magnetic field | the area surrounding a magnet where magnetic forces can be detected |
| electromagnetism | results when electric currents and magnetic fields interact with each other |
| electromagnet | wrapping a solenoid around an iron core makes this |
