A coil consists of `200` turns of wire having a total reistance of `2.0Omega`. Each turn is a square of side `18cm,` and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from `0` to `0.5t` in `0.80s`, what is the magnitude of induced emf and current in the coil while the field is changing?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the given parameters
- Number of turns (N) = 200
- Total resistance (R) = 2.0 Ω
- Side of the square coil (s) = 18 cm = 0.18 m (convert cm to m)
- Change in magnetic field (ΔB) = 0.5 T (from 0 to 0.5 T)
- Time interval (Δt) = 0.80 s
