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 5 `Omega`.

Explanation

To solve the problem, we will follow these steps:

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