Nondestructive Control of Objects Made of Electroconductive Materials in Pulsed Magnetic Fields

摘要

We have measured the values of the maximum tagential component of magnetic field strength H_(τm) on the surfaces of metal objects as a function of the time of increase in charge pulses and as a function of sample thickeness. We have found the empirical formulas of dependence H_(τSm) of the secondary field on sample thicknesses and on the time of increase in pulses, for which we give a theoretical explanation. We expound on methods for controlling the electric and magnetic properties of objects, as well as their geometric parameters and integrity defects in them.
