    Induced EMF, also known as electromagnetic induction or EMF Induction is the production of voltage in a coil because of the change in a magnetic flux through a coil.

    To calculate the induced emf:

    Magnetic flux = Magnetic field strength x Area = BA. Therefore ... Induced EMF = (change in Magnetic Flux Density x Area) / change in Time. If we want to increase the amount of EMF induced, we either ... The EMF induced is also proportional to the speed of the object going through the Magnetic Flux.
