This calculator estimates the temperature rise of a toroidal ferrite or powdered iron core.
The calculator does not do a lot of error checking, if you enter nonsense, it will produce nonsense. NaN means not a number, check the input values.
If you don't have reason to do otherwise, use exponent 0.833, an empirically derived value that is widely used.
