  • Copper and Electricity- how to generate electricity

    What Is Induction?Induction in CoilsFlux and Flux DensityInducing a voltageWe can induce a voltage in a wire using a magnetic field. We need to make the wire move through the field. We call the voltage the induced EMF (electromotive force). The faster the conductor moves through the field, the bigger the induced EMF. This is Faraday’s law.If we move the wire the other way, then the direction of the EMF will be reversed.The EMF will drop to zero if the wire: 1. stops moving or 2. is outside the magnetic field.The wire needs to be cutting through the...

  • Electricity Storage Energy and the Environment US

    About Electricity StorageElectricity Storage in The United StatesEnvironmental Impacts of Electricity StorageThe electric power grid operates based on a delicate balance between supply (generation) and demand (consumer use). One way to help balance fluctuations in electricity supply and demand is to store electricity during periods of relatively high production and low demand, then release it back to the electric power grid during periods of lower production or higher demand. In some cases, storage may provide economic, reliability, and environmental benefits. Depending on the extent to which it is...
