Figure shows a rectangular coil near a long wire. Calculate the mutual inductance of the combination is
- \(\frac{\mu_{0} \mathrm{a}}{2 \pi} \ln \left(1-\frac{\mathrm{b}}{\mathrm{c}}\right)\)
- \(\frac{\mu_{0} \mathrm{a}}{2 \pi} \ell \mathrm{n}\left(1+\frac{\mathrm{b}}{\mathrm{c}}\right)\)
- \(\frac{\mu_{0} \mathrm{a}}{\pi} \ell \mathrm{n}\left(1+\frac{\mathrm{b}}{\mathrm{c}}\right)\)
- \(\frac{\mu_{0} \mathrm{a}}{\sqrt{2} \pi} \ell \mathrm{n}\left(1+\frac{\mathrm{b}}{\mathrm{c}}\right)\)
Answer
