Inside an atom there is a nucleus and electrons that orbit around it. In many metals, the atoms have electrons that can detach from the atom and move around. These are called free electrons. Most metals, gold, silver, copper, all have free electrons. These electrical “conductors” make it easy for electricity to flow through them because of these free electrons. Electricity needs these conductive materials to move from place to place and to get electricity to move requires an electrical generator.
There is a link between electricity and magnetism. Electricity can produce magnetism and magnetism can produce electricity. This is why generators use magnets to get electricity moving. A magnet spins inside a coil of wire to get those free electrons moving around thus creating electricity. Generators can be very small or large depending on how much electricity is needed. A generator can be powered by a number of different sources including, but not limited to, wind, water, steam, heat, and other things.
Electricity is measured in amps, which is the number of electrons that move through a wire. One amp is equivalent to 6,240,000,000,000,000,000 electrons going... [continues]
