Term | Definition |
---|---|
Electricity | electric charges that flow through a wire or similar material |
Magnetism | the force of attraction or repulsion of magnetic materials |
Electric charge | a property of electrons and protons, electrons carry a negative charge and protons carry a positive charge |
Electric Current | the flow of electric charge through a material |
Electric generator | a device that uses motion and converts it into electric current |
Conductors | materials through which electrons move freely |
Molten | melted especially by intense heat |
Alternating current | current consisting of charges that move back and forth in a circuit |
Step-up transformer | a transformer that increases voltage |
Electromagnet | a strong magnet that can be turned on and off |
Insulators | materials through which charges of an electric current are not able to move freely |
Step-down transformer | a transformer that decreases voltage |
Electric Current | the flow of electric charge through a material |
Magnetic poles | the ends of a magnetic object, where the magnetic force is strongest |
Van Allen Belts | two doughnut-shaped regions that contain electrons and protons traveling at very high speeds |
Attract | to pull to or toward oneself or itself (electron-proton interaction) |
Magnetosphere | the region of Earth's magnetic field confined by solar wind |
Voltage | the difference in electrical potential between two places |
Electric generator | a device that uses motion and converts it into electric current |
Electrical potential | potential energy per unit of electric charge |
Transformer | a device that increases or decreases voltage |
Electric motor | a device that use electric current to produce motion |
Navigation | method of determining position, course and distance traveled |
Magnetic Compass | a device that has a magnetized needle that can spin freely, a compass needle always points north |
Electric Current | the flow of electric charge through a material |
Ohm's Law | ohms (resistance) = volts (voltage) / amps (current; R=V/I or I = V/R or V= IR |
