(a) Write down the integral form of Faraday's law (Maxwell's third equation) and briefly explain what is meant by each of the terms in the equation. (3 marks) (b) With reference to Faraday's law, what is meant by the terms motional emf and magnetic induction? (c) Consider a uniform magnetic field that is confined to a circular region with radius R, as shown in the figure below. Suppose the magnitude of B increases with time, i.e., dB/dt > 0. Find the electric field (in terms of dB/dt) induced by the changing magnetic field in the regions (i) r < R (ii) r > R. 11111 | T (2 marks) B (5 marks) (a) Write down the integral form of Faraday's law (Maxwell's third equation) and briefly explain what is meant by each of the terms in the equation.
