Question

Write biot-savart law for the magnetic field due to a current element in vector form.

Answer 1

A current carrying wire generates amagnetic field. According to Biot-Savart's law, the magnetic field at a point due to an element of a conductor carrying current is, Directly proportional to the strength of thecurrent, i. Directly proportional to the length of the element, dl.

Answer 2

${\huge{\mathfrak{Answer}}}$

The Biot-Savart's law gives the magnetic field produced due to a current carrying segment. The magnitude of the magnetic field dB at a distance r from a current carrying element dl is found to be proportional to I and to the length dl. And is inversely proportional to the square of the distance |r|.
