A square coil of 100 turns and side length 1 cm is rotating in a uniform magnetic field such that axis of rotation is perpendicular to magnetic field. If coil completes 1 rotation in 1ms.Find average EMF induced in `muV)` in half rotation. ( Magnetic field `( B) = 10^(-5) T ` ) .

Explanation

To solve the problem of finding the average EMF induced in a square coil during half a rotation, we can follow these steps:

### Step 1: Understand the given parameters
- Number of turns in the coil (N) = 100
- Side length of the square coil (a) = 1 cm = 0.01 m
- Magnetic field strength (B) = \(10^{-5}\) T
- Time for one complete rotation = 1 ms = \(1 \times 10^{-3}\) s
