    Help with this Q!

    If i gave you a magnetic flux vs time graph as a positive cosine non phase shifted function, that is its initially at a maximum. What is the induced emf graph?

    a negative sine function without any phase shift ie.y=-sinx, same amplitudes and period as the flux graph.

    Why is it not a positive sin non phase shift?, given that faradays law is (- n (change in flux) )

    my mistake you are right, i forgot when u differentiate cosine you get -sine. and then the -n makes it a positive sin no phase shift
