Question

I truly do not understand how to obtain the answers to this question. Please, when giving your answer explain why... I really want to understand. Here is the question:
A magnetic field B, directed along the z-axis, varies with time T as shown in the figure. A planar conducting loop is in the magnetic field. The magnetic field is perpendicular to the plane of the loop. Select the appropriate description for the magnitude of the EMF induced in the loop (EMF-mag) and for its direction (EMF-dir) at the indicated times. Select a response for each statement (choose from the options presented).
(greater than/less than/equal to/true/false) The EMF-mag at A is equal to zero.
(greater than/less than/equal to/true/false) The EMF-mag at C is ... that at G.
(greater than/less than/equal to/true/false) The EMF-mag at J is ... that at D.
(greater than/less than/equal to/true/false) The EMF-dir at F is opposite to that at J.
(greater than/less than/equal to/true/false) The EMF-dir at C is the same as at F.
(greater than/less than/equal to/true/false) The EMF-mag at L is ... that at H.
(greater than/less than/equal to/true/false) The EMF-mag at L is ... that at C.

Explanation / Answer

E (induced EMF) = change in B / change in time E will be greater where the slope of the graph is steepest at A   E > 0 at C E equals that at G at J E > than that at D at F same as at J at C opposite to that at F   (slope at one is positive and negative at the other) at L > H   since slope is steeper at L L < C   since slope at C is steeper than at L
