Extracted text: In the figure below, the magnetic flux that crosses the indicated turn decreases with time according to the expression OB = 4t + 2t¸ where OB is given in webers and t in seconds. (a) Calculate the modulus of the induced emf in the turn when t=2s; (b) Indicate the direction of current in the spirals, that is, say if it is clockwise or counterclockwise.
