A wire is formed into a shape of two half circles connected by equal length sections as shown in figure. A current flows in circuit clockwise as shown .What is the magnitude of the magnetic field induction at the centre.
- \(\frac{\mu_{0}\left(R_{1} \cdot R_{2}\right) I}{\left(R_{2}-R_{1}\right)}\)
- \(\frac{\mu_{0}\left(R_{1}-R_{2}\right) I}{4 R_{2} R_{1}}\)
- \(\frac{\mu_{0}\left(R_{1}+R_{2}\right) I}{4 R_{2} R_{1}}\)
- \(\frac{\mu_{0}\left(R_{1}-R_{2}\right) I}{2 R_{1} R_{2}}\)
Answer
(C) _ 0 (R_ 1 +R_ 2 ) I 4 R_ 2 R_ 1
