⚡ Longitudinal NDT (Coil Shot Amp-Turns NI = 45,000 / (L/D), Aspect Ratio Sizing)

MPI Coil Shot Longitudinal Magnetization Calculator

Calculate longitudinal magnetization ampere-turns ($NI = 45,000 / (L/D)$) for 5-turn encircling magnetic coils under ASTM E1444: evaluate component length-to-diameter aspect ratio ($L/D > 3$), eliminate demagnetizing end-effect flux leakage, detect transverse fatigue cracks across high-stress bolts and turbine shafts, and NDT engineering profits.
