To find the magnitude of the induced electric field \( E_n \) at a point \( r \) (where \( r > R \)) due to a time-varying magnetic field, we can follow these steps: ### Step 1: Understand the scenario We have a uniform magnetic field that is varying with time, and this magnetic field exists in a circular region of radius \( R \). The rate of change of the magnetic field is given by \( \frac{dB}{dt} = b \). ### Step 2: Apply Faraday's Law of Electromagnetic Induction According to Faraday's Law, the induced electromotive force (emf) in a closed loop is equal to the negative rate of change of magnetic flux through the loop: ...
