Two coaxial coils are very close to each other and their mutual inductance is 10 mH. If a current (60 A) sin 500t is passed in one of the coils, then find the peak value of induced emf in the secondary coil.

Explanation

To find the peak value of the induced emf in the secondary coil when a current is passed through the primary coil, we can follow these steps:

### Step 1: Understand the given values
- Mutual inductance (M) = 10 mH = 10 × 10^(-3) H
- Current (I) = 60 sin(500t) A

### Step 2: Write the formula for induced emf
The induced emf (E) in the secondary coil can be calculated using the formula:
