$A$ circular coil of area $200 \,cm^2$ and $50$ turns is rotating about its vertical diameter with an angular speed of $40 \,rad/s$ in a uniform horizontal magnetic field of magnitude $2 \times 10^{-2} \,T$. The maximum emf induced in the coil is (in $\,V$)

What is the phase difference between the flux linked with a coil rotating in a magnetic field and the induced emf produced in it?

In an $AC$ generator,a rectangular coil of $100$ turns each having area $14 \times 10^{-2} \, m^2$ is rotated at $360 \, rev/min$ about an axis perpendicular to a uniform magnetic field of magnitude $3.0 \, T$. The maximum value of the emf produced will be $............ \, V$. (Take $\pi = \frac{22}{7}$)

The $e.m.f.$ induced in a coil of wire,which is rotating in a magnetic field,does not depend on

The phase difference between the magnetic flux linked with a coil rotating in a uniform magnetic field and the induced $e.m.f.$ produced in it is

Write down the formula for the induced $emf$ in an $AC$ generator and discuss how it varies with time.
