Term | Definition |
---|---|
electric charge | a property that leads to electromagnetic interactions between the particles that make up matter |
static electricity | the buildup of electric charge on an object |
electric conductor | a material through which charges can move freely |
electrical insulator | a material through which charges cannot move easily |
semiconductors | a special class of materials 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 |
electric circuit | a complete, closed path through which electric charges flow |
series circuit | all parts are connected in a row that forms one path for the electric charges to flow |
parallel circuit | electric charges have more than one path they can follow |
magnet | any material that attracts iron or objects made of iron |
magnetic force | a push or pull |
magnetic poles | ends of magnets |
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 | a solenoid wrapped around an iron core |
