    physics helps

    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...
