Inductance Of Metal Sheet

L d 2 n 2 l 0 45d μh where d is the coil diameter in meters n the number of turns and l the coil length in meters.

Inductance of metal sheet.

This suggests the presentationof the resultsin sucha way asto enablethe radius. What this means to most folks is high inductance is good for thicker metals where good wetting at the toes of the weld is a priority and low inductance works better on thin metal. Regarding current sheet inductance formulas for single layer coils one of the most widely known is the one by wheeler which states after converting to metric units.
