Question

What is Biot-Savart Law?

Answer

Biot-Savart Law – Biot-Savart law gives the magnitude of magnetic field at any point due to a current carrying conductor.
According to Biot-Savart law, magnetic field dB at any point P due to a current element IdI is dB = μ₀/4π × I(d1 × r^)/r² = μ₀/4π × I(d1 × r)/r³ = kIdl sinθ/r² [∵ μ₀/4π = k]
