Homework Help: Emf and windings

  1. Oct 31, 2012 #1
    How many windings you have to reel up on a cylinder (length is 60cm and the diameter is 5cm) so that a Emf of 6mV gets induced if ΔI/Δt=1A/s?

    This is not my homework. I was doing this as a preparation. I know the formula:
    L is unknown. How to relate it to the windings, the length and the diameter of the cylinder?
