Magnetic flux linked with each turn of a 25 turns coil is 6 milliweber. The flux is reduced to 1 mWb in 0.5s. Find induced emf in the coil.

Explanation

To solve the problem of finding the induced emf in a coil with 25 turns, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Initial magnetic flux per turn, \( \Phi_i = 6 \, \text{mWb} = 6 \times 10^{-3} \, \text{Wb} \)
- Final magnetic flux per turn, \( \Phi_f = 1 \, \text{mWb} = 1 \times 10^{-3} \, \text{Wb} \)
- Number of turns in the coil, \( N = 25 \)
