Abstract
Some embodiments of the invention may include an eddy current nondestructive evaluation device. The eddy current nondestructive evaluation device may include a rotating body; a motor coupled with the rotating body such that the motor rotates the rotating body; a permanent magnet coupled with the rotating body; a pickup coil coupled with the rotating body; and an integrator circuit electrically coupled with the pickup coil that integrates a voltage from the pickup coil to produce integrated voltage data.
