    • Faraday's law states that the magnitude of the induced e.m.f is directly proportional to the rate of change of magnetic flux linkage
    • e.m.f is dp to magnetic flux linkage / time
    • Faradays law can be written as an equation where the constant of proportionality is a minus sign.
    • Lenz's law states that the direction of the induced e.m.f or current is always such as to oppose the change producing it.
