[QUOTE="hidemi, post: 6461908, member: 686975"] [B]Homework Statement:[/B] A rectangular wire loop (length = 60 cm, width = 40 cm) lies completely within a perpendicular and uniform magnetic field of magnitude of 0.5 T. If the length of the loop starts increasing at a rate of 20 mm/s at time t= 0, while the width is decreasing at the same rate, what is the magnitude of the inducede mf at time t= 4.0 s? a.6.8 mV b.5.2 mV c.3.6 mV d.8.4 mV e.10 mV Answer: C [B]Relevant Equations:[/B] dΦB/dt = dB/dt*A I did the question in this way as attached. I got the crrect answer, but I feel unsure if it is the right way of doing it. [/QUOTE]
