bRIEF ME ABOUT bIOT SAVART lAW
Thanks Mr Rao for your question.
Biot-Savart Law is a law of Physics, specifically electromagnetism. It is an equation describing the magnetic field generated by a stationary electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. This equation or the law is named after the French scientists Jean-Baptiste Biot and Félix Savart.
I would strongly advise you to check out this video-illustration to have a better understanding of the law. https://study.com/academy/lesson/the-biot-savart-law-derivation-examples.html
