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
- A linearly
- B exponentially
- C sinusoidally
- D laterally
Answer & Solution
Correct Answer
(C) sinusoidally
Step-by-step Solution
Detailed explanation
When a rectangular coil is rotated in a uniform magnetic field about an axis passing through its centre and perpendicular to field, then magnetic flux associated with coil is given as \(\phi=B A \cos \theta=B A \cos \omega t\) ...(i) \(\therefore\) Induced emf,…
