Physics - EMI/AC Question with Solution | TestHub

Two straight conducting rods are connected by flexible conducting wires to form a rectangular outline (figure i). The sides of the rectangle are $\mathrm{a}=30\mathrm{cm}$ and $\mathrm{b}=50\mathrm{cm}$. The circuit is placed in a uniform magnetic field with induction $\mathrm{B}=5\times 10^{-3}\mathrm{T}$ directed perpendicular to the plane. What is the charge $\Delta \mathrm{q}$ (in $\mu \mathrm{C}$ ) that flows along the contour, if you turn it by 180° symmetrically as shown without the wires touching each other (figure ii)? Loop resistance $\mathrm{R}=1\mathrm{ohm}$. Take self-inductance of the system to be $\mathrm{L}=1\mathrm{H}$. Find $\frac{\Delta \mathrm{q}}{150}$.
