- We already know now that current carrying conductor generates magnetic field around themselves. Biot-Savart law just mathematically states the intensity of this magnetic field at a point.
- According to the Biot-Savart law, magnetic field dBdue to current element idl, at a point P situated at distancer from the current element idl,is:
i) directly proportional to the current element idl, ii) directly proportional to the sine of the angle (θ) between current element and r, and iii) inversely proportional to the square of the distance r between current element and the point
dB∝idl (sinθ)/r2
dB = (μo/4π)×idl×(sinθ)/r2
dB = idl × r / r3
