The modification and discretization for H/spl I.oarr/-/spl psi/ functional in three dimensional eddy current field

The error resulting from the existent H/spl I.oarr/-/spl psi/ method (magnetic field intensity vector-scalar magnetic potential) of three dimensional eddy-current field was discovered by practical computation. The corresponding modified method was given. The modified H/spl I.oarr/-/spl psi/ was discretized. A correct result was obtained by calculating a practical three dimensional eddy-current problem.
