|---|---|
| Electric Charge | property that leads to electromagnetic interactions between the particles that make up matter. |
| Static Electricity | buildup of electric charge on an object. |
| Electrical conductor | material through which charges can move freely |
| electrical insulator | material through which charges cannot move easily |
| Semiconductors | special class of material;s that conduct electric charge better than electrical insulators better known as electrical conductors |
| electric current | rate of flow of electric chages |
| voltage | amount of work required to move each unit of charge between two points |
| electrical circuit | 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 charge flow |
| parallel circuit | electric charger have more than one path that they can follow |
| magnet | any material that attracts iron or objects made of iron |
| magnetic force | when you bring two magnets together they exert push or pull |
| magnetic poles | two magnets can push each other apart because of their ends |
| magnetic field | the area surrounding a magnet where magnetic forces can be detected |
| Electromagnetism | when electric currents and magnetic fields interact with each other |
| solenoid | a coil of wire that carries and electric current and therefore produce a magnetic field |
| electromagnet | wrapping a solenoid around an iron core |
| electric motor |
