| Question | Answer |
|---|---|
| electric charge | a property that leads to electromagnetic interactions between the particles that make up matter |
| static electricty | buildup of electric charge on an object |
| electrical conductor | a material through which charges can move freely |
| electrical insulator | a material through which charges cannot move easily |
| semiconductors | special class of material that conduct electric charge better than electrical insulators but not as well as electrical conductors |
| electric current | the rate of flow of electric charges |
| voltage | the amount of work required to move each unit of charge between two points |
| resistance | the opposition to the flow of electric charge |
| 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 flow |
| parallel circuit | electric charges that have more than one path that they can follow |
| magnet | any material that attracts iron or objects made of iron |
| magnetic force | two magnets that exert a push or pull on each other |
| magnetic poles | two magnets that can push each other apart because of their ends |
| magnetic field | the area surrounding a magnet where magnetic forces can be detected |
| electromagnectism | a relationship between electricity and magnetism |
| electromagnetic | wrapping a solenoid around an iron core |
