Dynamic diagnosis of conductive materials on the basis of force acting on the sensor made of permanent magnet

Checking the quality of the material during the manufacturing process causes problems. The impact of motion in conjunction with the magnetic field induces eddy currents and forces. They affect the field source element through the dynamic forces occurring in the process of movement. The value of the impact force may indicate material defects arising during the manufacturing process. The use of this phenomenon may assist in the quality control of the produced materials. The paper presents the simulation of such a phenomenon and calculations of the forces and torques occurring in this type of process. The calculations were accomplished in ANSYS environment using the Finite Element Method and Maxwell Stress Tensors Method.
