# What is Bio Savart’s law? and who discovered it

What is the law of Bio-Savart, French scientist Bio and Savart in 1820 formulated a law to find the intensity of the magnetic field at a point near the current carrying conductor, which is called Bio Savart Law it is said.

## What is Bio Savart’s law

We have known what is the law of Bio-Sawt, but we also know it in another definition, the law by which the intensity of the magnetic field can be determined. Bio Savart’s law It is called

### Prove Bio Savart’s Law

Let x and y be a conducting wire in which I current is flowing. Take a fraction of the length dl in the wire. in which the point p lies at a distance r.

The intensity of the magnetic field at point p depends on the following factors.

1. is directly proportional to the current. dB I
2. is directly proportional to the length of the minority. dB dl
3. The length of the subsample is directly proportional to the angle formed by the line joining the point p. dB sin
4. is inversely proportional to the square of the distance from the minority to the point p. dB 1/r

Combining all of the above

dB Idlsinθ/r² dB = k Idlsinθ/r² where k is a constant that depends on the method of measurement.

in CGS method– k = 1, dB = Idlsinθ/r² Gauss in air or vacuum

in SI system– k = 10⁻⁷ = μ0/4π, dB = μ0/4π. Idlsinθ/r² Tesla
