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 : -**

F_{e}=B*l*i*sin θ

The meaning of various symbols in above formula can be given as,

F_{e}= Net Electromagnetic force produced in Newtons

B = flux density, in Wb/m^{2} 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. **
