Question

A coil of area $$A$$ and $$N$$ turns is rotating with angular velocity $$\omega$$ in a uniform magnetic field $$\mathbf{B}$$ about an axis perpendicular to $$\mathbf{B}$$. Magnetic flux $$\phi$$ and induced emf $$\varepsilon$$ across it, at an instant when $$\mathbf{B}$$ is parallel to the plane of the coil, are:

Accepted Answer

C. $$\phi = 0, \, \varepsilon = NAB\omega$$

Answer

A. $$\phi = AB, \, \varepsilon = 0$$

Answer

B. $$\phi = 0, \, \varepsilon = 0$$
