Abstract

Abstract: The equation of the magnetic line of force induced by a circular current is derived. The distributional pattems satisfying the equation are drawn by mathematical software MatLab. The formula for magnetic induction is deduced by following B=↓△×A. The patterns of the magnetic induction B are drawn by the software.
