This article focuses on munication theory and practice, for each parameter selection, the range of each factor, have been seriously thinking to the teacher about then calculated, in the calculation, but also try to bine engineering and ensure that errors in engineering to the extent permitted. The final calculation results to the national standard, pleted the calculation of electromagic transformer.
