wht is the biot-savart’s law and tell how many applications are there in this law?and give equations of applications?

dear salvanth,

           the biot-savart law is defined as the magnetic intensity at any point due to a steady current in an infinetely long straight wire is directly proportional to the current and inversely proportional to the distance from point to wire.

 

In physics, specifically electromagnetism, the Biot–Savart law (/ˈbiːoʊ səˈvɑːr/ or /ˈbjoʊ səˈvɑːr/)^[1] is an equation describing the magnetic field generated by an electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The law is valid in the magnetostatic approximation, and is consistent with both Ampère's circuital law and Gauss's law for magnetism.^[2] It is named after Jean-Baptiste Biot and Félix Savart who discovered this relationship in 1820.
