A rectangular coil of area `50cm^(2)` and `100` turns is placed perpendicular to a magnetic field of `10^(-2)Wb//m^(2)`. If the coil is withdrawn from the field in `40` ms, calculate the emf induced.

Explanation

To solve the problem, we need to calculate the induced electromotive force (emf) in a rectangular coil when it is withdrawn from a magnetic field. Here’s the step-by-step solution:

### Step 1: Understand the given data
- Area of the coil, \( A = 50 \, \text{cm}^2 \)
- Number of turns, \( N = 100 \)
- Magnetic field strength, \( B = 10^{-2} \, \text{Wb/m}^2 \)
- Time taken to withdraw the coil, \( t = 40 \, \text{ms} \)
