Ampere’s law. using an adaptation of a MatLab-routine for numerical solution of the Biot-Savart Law (1). Meshgrid and Vectors in 2D. The course is taught with an emphasis on engineering applications. A Lagrangian particle method for scalar transport on the sphere Velocity from Biot-Savart Law. Coulomb's law, Gauss's law, electrical potential, dielectric materials capacitance, boundary value problems, Biot-Savart law, Ampere's law, Lorentz force equation, magnetic materials, magnetic circuits, inductance, time varying fields and Maxwell's equations. the Biot-Savart Law, expressed as a discrete summation, again provide additional ins ight for more practical problems in magnetostatics. If we wish to find the electric field at a distance l from the center of the loop due to a small element ds, we can use the Biot-Savart Law as:.
