Can anyone tell me how to draw the graph for physics paper 4, oct/nov 05, question 6? thank in advance.

i give you the clue ..

magnetic flux linkage=B x A
THEREFORE magnetic flux linkage is proportional to B.
so magnetic flux linkage against time graph is the same as B against time.
since E(emfinduced)= - dmagneticfluxlinkage / dtime (faraday +lenz law)
so, gradient of magnetic flux linkange against time graph is emf induced .

notice the -ve sign ya. if still don't know, find me lor.. =)
