Consider a current carrying loop shown in figure formed by radial lines and segments of circle whose centers are at point P.What is the magnitude of magnetic field induction at point P.
- \(\frac{\mu_{0} \mathrm{I}}{3}\left(\frac{1}{\mathrm{a}}-\frac{1}{\mathrm{~b}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{6}\left(\frac{1}{\mathrm{a}}-\frac{1}{\mathrm{~b}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{12}\left(\frac{1}{\mathrm{a}}-\frac{1}{\mathrm{~b}}\right)\)
- \(\frac{\mu_{0} \mathrm{I}}{4}\left(\frac{1}{\mathrm{a}}-\frac{1}{\mathrm{~b}}\right)\)
Answer
(C) _ 0 I 12 ( 1 a - 1 ~b )
