I've created this program that calculates the magnetic field at a distance d_x, d_y, d_z from a point that dists b from the coil plane, but when i substitute it for d_x=d_y=d_z=0 it is incongruent with the biot savart's approximation:. The expression is an idealization to an infinite length solenoid, but provides a good approximation to the field of a long solenoid. µ 0 (= 4π x 10-7 Weber/meter-Ampère) is a constant, the permeability of a vacuum; is the I current in ampères (or Amps); d is an elemental vector along the direction of current flow with the unit of length in meters; r. However in symmetric cases it is more convenient to use amperes law for determining the magnetic field. Fundamental Postulates of Magnetostatics in Free Space. Law of Biot and Savart Magnetic Field of Circular Current Magnetic Field Applications (2) Magnetic Field on the Axis of a Solenoid Magnetic Field Generated by Current in Straight Wire (3) Magnetic Field at Center of Square-Shaped Wire [tsl518]. The law was actually derived to relate a magnetic field induced by an electric current in a wire, but it can also be used to estimate the circulation of flow around a wing. Savart) A law defines the contributions to a magnetic field through an electric current. Ampere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.
