Re: Inductance Calculations for iron core Post Script


If you'll be using the inductor for current control, consider making the
core bundle movable.  Wind a few more turns of wire than you figure you
need . . . to give you some adjustment range.  You can even achieve
automatic regulation, if the coil is allowed to pull the core in against
a spring, gravity or a counter-weight.  (It may hum a little, but will
give you a visual indication of current also).
