Description:

Biot-Savart’s law is given by -

dB =
μ0/4π
idlsinθ/r2

Boit-Savart\'s

Vector form of Biot-Savart’s law is given by –

dB =
μ0/4π
i
dl→ × r→/|r3→|

Magnetic field due to current carrying wire is given by -

B = ∫ dB =
μ0/4π
idlsinθ/r2

S.I. unit of B is tesla.

Vector form of magnetic field due to a current carrying wire is given by –

B→ = ∫
μ0/4π
i(dl→ × r→)/r3
