“…The first task is the identification and investigation of the effects of operational variables, including the test rig velocity [45]. Work has been done on probe velocity effects in NDE [40,[46][47][48][49][50][51][52][53][54][55]. However, most research on moving magnetic field problems has been carried out in other areas rather than NDE, such as electric machinery [56][57][58][59][60][61][62], electromagnetic lévitation [63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78], electromagnetic launcher [78][79][80][81], and electromagnetic brakes [82,83].…”
