In some litterature this formula is used: Bmax = Vmax/ (2*pi*f * A * n) Where Bmax is the max magnetic flux density, Vmax is the max voltage over a coil with n turns wound on a toroid core with area A. 2*pi*f is the rate of voltage change per time unit. It looks like the magnetic flux...

Some sources say that magnetic flux density is not related to current but to VOLTAGE. I don't understand why. I always thought that the magnetic field in a wire is caused by the movement of charged elements (e.g electrons) in a wire. Can you explain this?
