Abstract
The method proposed for calculation a coil in free space is presented. Eddy current transducer mathematical model as a spiral flat inductor in free space is designed as example. It allowed to calculate its impedance, considering skin effect in conductor and to estimate its quality. The model is obtained with assump-tions about current distribution in a conductor using the discrete Hankel transform that re-duces machine time significantly. Current distribution function is based on phenomena re-versibility in nature, namely, electromagnetic field creates definite current distribution in conductive medium and such current distribution in conductive medium creates the same electromagnetic field in free space. Flat inductor impedance and coil quality at 1 MHz and DC are calculated.
