To find the magnitude of the induced electric field \( E_n \) at a point \( r \) (where \( r > R \)) due to a uniform but time-varying magnetic field, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We have a uniform magnetic field that is changing with time, represented as \( \frac{dB}{dt} = b \). This magnetic field exists in a circular region of radius \( R \). We need to find the induced electric field at a point outside this region, specifically at a distance \( r \) where \( r > R \). 2. **Use Faraday's Law of Electromagnetic Induction**: ...
