Find Magnetic Field Due to Current

The calculator will calculate the magnetic field due to current in the wire using Biot Savart Law based on given values.

N A-1 m-1

Formula:

Magnetic Field (B) = (μ0 / 4π) (Q v sinθ / r2)

Where,

      μ0 = Permeability of a vacuum (4π x 10-7 N A-2),

      Q = Point Charge,

      v = Velocity,

      r = Distance,

      θ = Angle between v and r

The Biot Savart Law defines fundamental quantitative relationship between an electric current and the magnetic field it produces, based on the experiments in 1820 of the French scientists Jean-Baptiste Biot and Félix Savart.

The Biot-Savart law is applied in a specific case by adding up the contributions to the magnetic field at a given point from the whole series of short current segments that constitute a specific conductor of whatever shape
