What is the value of the magnetic field induction at the point P mentioned in the figure?
- \(\frac{\mu_{0} \mathrm{I}}{4 \pi}\left(\frac{3 \pi}{2 \mathrm{R}}+\frac{\sqrt{2}}{\mathrm{~d}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{2 \pi}\left(\frac{3 \pi}{2 \mathrm{R}}+\frac{\sqrt{3}}{\mathrm{~d}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{4 \pi}\left(\frac{3 \pi}{4 \mathrm{R}}-\frac{\sqrt{3}}{\mathrm{~d}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{3 \pi}\left(\frac{3 \pi}{4 \mathrm{R}}+\frac{\sqrt{2}}{\mathrm{~d}}\right)\)
Answer
(A) _ 0 I 4 ( 3 2 R + 2 ~d )
