Physics - EMI/AC Question with Solution | TestHub

In the given figure a uniform magnetic field ${\mathrm{B}}_0$ exist in outward direction and the wire CD of resistance R is fixed and wire OA and OB rotating with angular speed $\omega$ as shown in figure both are conducting wire, if at any instant $\mathrm{OA}=\mathrm{OB}=\ell$ and making an angle of 30° with y-axis each then find the current in wire AB.
