1. A circular loop of wire has a radius that increases according to r = ro(1+at), where a and ro are constants. The loop is in a region of space with a uniform magnetic field Bo oriented at 0 from the normal to the plane of the loop, as shown in the figure below. (a) Find the induced emf in the loop. (b) Looking at the loop from the right side, what is the direction of the induced current. Justify your choice. Bo 1.
