Question 66: Electromagnetic Induction

Question

Two conducting circular loops A and B are placed in the same plane with their centres coinciding as shown in figure. The mutual inductance between them is:

Accepted Answer

$$\begin{aligned}
& \frac{\phi_{A / B}}{I_B}=M \
& \Rightarrow \quad M=\frac{\mu_0 I_B 	imes \pi a^2}{2 b 	imes I_B} \
& =\frac{\mu_0 \pi a^2}{2 b}
\end{aligned}$$

Answer

$$\frac{\mu_o}{2 \pi} \cdot \frac{b^2}{a}$$

Answer

$$\frac{\mu_{\mathrm{o}} \pi \mathrm{a}^2}{2 \mathrm{~b}}$$

Answer

$$\frac{\mu_0 \pi b^2}{2 a}$$

Answer

$$\frac{\mu_0}{2 \pi} \cdot \frac{a^2}{b}$$
