The current through a coil of inductance 5 mH is reversed from 5A to `-5A` in 0.01 s. What is the maximum self-induced emf in the coil?

Explanation

To solve the problem of finding the maximum self-induced emf in a coil when the current is reversed, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values:**
- Inductance (L) = 5 mH = 5 × 10^(-3) H
- Initial current (I_initial) = 5 A
- Final current (I_final) = -5 A
