Abstract
The simplified expressions for the electromagnetic field of the near zone from the magnetic frill are derived. In these formulas, 
and 
are expressed as a single integration of the complete elliptical integrals of the first and second kinds. Furthermore the closed form of 
is obtained approximately. Their accuracy is checked numerically by comparing with Tsai\´s, and significant improvement in efficiencies is obtained.
