Numerical analysis of eddy current transducer with rotating permanent magnets for planar conducting plates testing
The aim of this paper is to present the numerical simulations of a novel eddy current transducer designated for inspection of planar conducting specimens. The transducer consists of the rotating head with permanent magnets which is used to induce the eddy currents in the tested material. The Hall effect device is used to measure changes of a magnetic field caused by the eddy current reaction. Numerical simulations, utilizing a finite element method (FEM) and the COMSOL application, of the transducer is presented in case of an aluminum specimen with different defects.
