At which position of the plane of the rotating coil with the direction of magnetic field the e.m.f induced in the coil is maximum ?

Explanation

To determine the position of the plane of a rotating coil where the induced electromotive force (e.m.f) is maximum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Induced EMF**:
The induced e.m.f in a coil is given by Faraday's law of electromagnetic induction, which states that the e.m.f is equal to the rate of change of magnetic flux through the coil.

2. **Expression for Magnetic Flux**:
