Question
(10%) Problem 6: Two rectangular loops are in a magnetic field. Loop 1 has area A1 = 0.55 m^2 and loop 2 has area A = 0.065 m^2. The magnetic field changes with time as B(t) = Ct. where C = 0.35 T/s. Part (a) Calculate the magnitude of the induced emf in loop E1. &1 in V. Part (b) What?s the direction of the current induced by e1? -The flux is increasing in this loop, which means the induced magnetic field will be out of the page. Part (e) Calculate the ma2nitude of the induced emf in loop 2. E2. in V. Part (d) What?s the direction of the current induced by e?Explanation / Answer
induced emf e2 = NA2 dB/dt
where A2 is the area of second loop
emf 2 = 1 * 0.065 * 0.35
emf 2 = 0.02275 Volt
