The magnetic flux through a coil perpendicular to its plane is varying according to the relation `phi_B = (5t^3 +4t^2 +2t-5)` weber. Calculate the induced current through the coil at t = 2 second. The resistance of the coil is `5Omega`

Explanation

To solve the problem of finding the induced current through the coil at \( t = 2 \) seconds, we will follow these steps:

### Step 1: Write down the expression for magnetic flux
The magnetic flux \( \phi_B \) through the coil is given by:
\[ \phi_B = 5t^3 + 4t^2 + 2t - 5 \quad \text{(in Weber)} \]
