Web4 M. A. Biot then derive corresponding variational principles. This implies a prior knowledge of the equations that govern the continuous field, and each particular case must then be treated separately with its own boundary conditions. In this context the deeper unitary physical insight is lost. By WebThis law enables us to calculate the magnitude and direction of the magnetic field produced by a current in a wire. The Biot-Savart law states that at any point P ( Figure 12.2 ), the magnetic field d →B d B → due to an element d →l d l → of a current-carrying wire is given by. d →B = μ0 4π Id→l ×^r r2. d B → = μ 0 4 π I d l ...
