摘要：
An analytical modeling is presented for the axially symmetric pulsed eddy currents produced by the driver coil in a ferromagnetic plate with a flat-bottom hole (FBH) defect. The induced voltage in the pickup coil calculated by the analytical model has been compared with signal calculated by numerical model. The results show good agreement.
