A pair of adjacent coils has a mutual inductance of 1.5. H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change in flux linkage with the other coil?

Explanation

To solve the problem, we need to find the change in flux linkage with the other coil when the current in one coil changes. We can use the formula for mutual inductance and the change in current to find this.

### Step-by-Step Solution:

1. **Identify Given Values:**
- Mutual Inductance (M) = 1.5 H
- Initial Current (I1) = 0 A
- Final Current (I2) = 20 A
