Abstract: The mathematical analysis in the foundation of Blot-Savart Law reveals that the Biot-Savart law can be deduced directly from the second experiment designed by Blot.Thus the second experiment is a graceful experiment and has special value in physics teaching from the mathematical viewpoint.

Key words: Biot-Savart law, current element, steady current
