An AC generator consists of a coil of 100 turns and is of cross-sectional area $$3 \mathrm{~m}^2$$. It is rotating at a constant angular speed of $$60 \mathrm{~rads}^{-1}$$ in a uniform magnetic field of $$0.04 \mathrm{~T}$$. Resistance of the coil is $$360 \Omega$$. What is the maximum power dissipation in the coil?

Assertion (A) Magnetic flux is a vector quantity.

Reason (R) Value of magnetic flux can be positive negative or zero.

The induced emf cannot be produced by

Assertion (A) When plane of coil is perpendicular to magnetic field, magnetic flux linked with the coil is minimum, but induced emf is zero.

Reason (R) $$\phi=n A B \cos \theta$$ and $$e=\frac{d \phi}{d t}$$
