- Theory When charged particles flow through a given magnetic field, force is exerted on them. Likewise, charged particles that are in motion induce magnetic fields around the conductor in which they flow. Biot-Savart law is stated by the formula shown below; dB=μo IdL*r4πr3 In the formula, µo represents the permeability of free space, r represents vector displacement pointing from the section of the wire carrying current to the point whose magnetic field is being determined, and dl refers to a vector quantity with the value equal to the length of the segment of current. ...
