Abstract
Some problems owing to the magnetic field distribution often occur in magnetic powder flaw detection. For example, magnetic flux density concentrates locally because of geometry and configuration of magnetization equipment, and hence incorrect detection is caused. To overcome the problem two different techniques have been applied to a model of a square steel billet. The solution was obtained by using an AC nonlinear FEM analysis
