The magnetic field through a single loop of wire 14.0 cm in radius and of 11.5 Ω resistance changes with time as shown in the figure. Calculate the emf in the loop as a function of time. a)What is the emf at t = 1.0 s? For the sign take the loop in the plane of the paper, and the magnetic field out of the paper. Take clockwise to be positive emf. b)What is the emf at t = 3.0 s? c)What is the emf at t = 5.0 s? d)What is the current at t = 1.0 s?
