The magnetic flux through the loop shown in the figure increases according to the relation ϕB=6.0t2+9.0t where ϕB is in mill-webers and t is in seconds.
a. What is the flux at t = 3.0 s? What is the direction of the current, clockwise or counterclockwise?
b. What is the magnitude of the emf induced in the loop at t = 3.0 s?
