When a rectangular coil is rotated in a uniform magnetic field about an axis passing through its centre and perpendicular to the field,the emf induced in the coil varies

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

Which statement is correct for the phenomenon of periodic electromagnetic induction in a rotating coil?

When a wire loop is rotated in a magnetic field,the direction of induced $emf$ changes in every

Discuss the principle and construction of an $A.C.$ generator (dynamo). Derive the formula for the induced $emf$ in an $A.C.$ generator.

An elliptical loop having resistance $R$,semi-major axis $a$,and semi-minor axis $b$ is placed in a magnetic field as shown in the figure. If the loop is rotated about the $x$-axis with angular frequency $\omega$,the average power loss in the loop due to Joule heating is:
