Question

For a coil rotating in a uniform magnetic field, the phase difference between the magnetic flux linked with the coil and the current induced in it is

• A. \(90^\circ\)
• B. \(180^\circ\)
• C. \(60^\circ\)
• D. \(360^\circ\)

Hint:

If \[ \Phi=\Phi_0\cos\omega t, \] then \[ \boxed{ e=-\frac{d\Phi}{dt}\propto\sin\omega t } \] Hence, the induced current leads the magnetic flux by \[ \boxed{90^\circ.} \]

Answer 1

The Correct Option is A
