A coil of inductance `1.0 H` and resistance `100 Omega` is connected to a battery of emf `12 V`. Find the energy stored in the magnetic field associated with the coil at an instant `10 ms` after the circuit is switched on.

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Identify the given values
- Inductance, \( L = 1.0 \, \text{H} \)
- Resistance, \( R = 100 \, \Omega \)
- EMF of the battery, \( E = 12 \, \text{V} \)
- Time after switching on the circuit, \( t = 10 \, \text{ms} = 10 \times 10^{-3} \, \text{s} \)
