Assalamoalaikum wr wb!
I just did this question...
ummm I used Faraday's law...phi is proportional to B
and E is proportional to rate of flux linkage do/dt
so E will be the gradient of the graph above...that's what i did..i dunno if it's wrong ....

E= Nd phi/ dT
phi is directly proportional to B like xpf memeber rightly quoted.
b is directly proportional to current I as seen in the formula:-
B=uI/2 pie a
hence the gradient of I/T graph would give Emf. but in the negative axis as you dont have to forget the minus sign there!
