For the wire arrangement in the figure, a = 14.4 cm and b = 18.9 cm. The current in the long straight wire is given by i = 6.70t - 13.9t. where i is in amperes and tis in seconds. (a) Find the emf in volts in the square loop at t = 3.91 s. (b) What is the direction of the induced current in the loop?
