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 |
