WebEither moving a wire through a magnetic field or (equivalently) changing the strength of the magnetic field over time can cause a current to flow. How is this described? There are two key laws that describe electromagnetic induction: Faraday's law, due to 19ᵗʰ century physicist Michael Faraday. WebThe potential difference tells you how much energy per coulomb the charges have to lose. Potential difference is measured in volts, symbol V, where 1 volt is equivalent to an energy difference of 1 joule for each coulomb of charge. Potential difference is commonly referred to as voltage.
