Dave Gordon: Transformer Current and Power at https://www.youtube.com/watch?v=qok2QdOfK4A Np*Ip/Ns*Is = Ep*Ip/Es*Is AmpereTurns_primary/AmpereTurns_secondary = VoltAmperes_primary/VoltAmperes_secondary Ampere Turns is the unit for the magnetic field. Multiply by the magnetic permeability and it gives magnetic field in Tesla. If you use a variable power supply with constant voltage source or constant current source, it will show the input
