This law explains Force experienced by a current carrying conductor due to magnetic field.
Friends,
We have already discussed Faraday's law of Electro-Magnetic Induction. It was all about the induction of e.m.f. in an electric circuit. Now we will discuss Biot Savart's law.
Biot Savart Law is also a very important concept from the point of view of Electric Machine Design. Biot Savart law is for Magnetic field in a similar way Coulomb's law is for Electric Field. Basically it gives a relation of Magnetic Field produced in a circuit/coil to the electric current it carries. The law also deals with the force produced on account of interaction between a magnetic field and a current carrying conductor.
According to Biot Savart's law the electromagnetic force Fe is give by the formula : -
Fe=B*l*i*sin θ
The meaning of various symbols in above formula can be given as,
Fe= Net Electromagnetic force produced in Newtons
B = flux density, in Wb/m2 or in Tesla ;
l = length of the conductor in meter ;
i = current carried by the conductor in Ampere ;
θ = angle between the direction of current and the direction of magnetic field.
The direction of the force produced is perpendicular to both current and magnetic field.
