Biot savart law hyperphysics
WebMar 8, 2015 · A couple of decades ago, I worked out a derivation of Biot Savart's law based on Coulomb's law, and relativistic length contraction. This is analogous to how you can derive the force between two current carrying wires as being due to the different reference frames for the moving and stationary charges (in the wire) causing Lorentz contraction, … WebApr 20, 2015 · The general formulation to the Biot-Savart law was given by P. Laplace. The expression of the Biot-Savart Law (the integration) shows that the principle of superposition is already included in it. Maxwell equations were developed later and they were designed suitably to encompass the implications of the Biot-Savart's law.
