Magnetic field intensity (B) due to current carrying conductor can be calculated by use of Biot-Savart law. Which is B = (μ0/4π) Idl x r/r3 where dB is magnetic field due current element Idl at a position r from current element. For straight wire carrying current magnetic field at a distance R from wire is B(μ0/4π) I/R (sin α + sin β) And magnetic field due to a circular arc at its center is B = (μ0I/4πR).θ where angle of circular arc at center, R is radius of circular arc. Now answer the following questions.
The magnetic field at C due to curved part is
