Question

Find the magnetic field at the point P in figure. The curved portion is a semicircle connected to two long straight wires. (A) (μ0 i/2 r)(1+(1/π)) (B) (μ0 i/2 r)(1+(2/π)) (C) (μ0 i/2 r)((1/2)+(1/π)) (D) (μ0 i/2 r)((1/2)+(1/2 π))

B P =((μ0 i/4 r)+(μ0 i/4 π r))=(μθ i/2 r)((1/2)+(1/2 π))

Q. Find the magnetic field at the point $P$ in figure. The curved portion is a semicircle connected to two long straight wires.

$\frac{μ _{0} i}{2 r} (1 + \frac{1}{π})$

$\frac{μ _{0} i}{2 r} (1 + \frac{2}{π})$

$\frac{μ _{0} i}{2 r} (\frac{1}{2} + \frac{1}{π})$

$\frac{μ _{0} i}{2 r} (\frac{1}{2} + \frac{1}{2 π})$

$B_{P} = (\frac{μ _{0} i}{4 r} + \frac{μ _{0} i}{4 π r}) = \frac{μ _{θ} i}{2 r} (\frac{1}{2} + \frac{1}{2 π})$
