Yet another round coil calculator, but with a difference. Mine works off-line, and in a continuous loop. Like that because it allows easy-peasy design by trial-and-error. Enter a first set of trial values, then just use the up/down arrow keys to scroll a factor in either direction. See instant results on-the-fly with no need of ever clicking a 'calculate' button. Requires the free LabVIEW Run-Time Engine. But once you have that, all my other calculators will likewise run.
