    I have question about the suggested answer by Vicphysics.

    When I was young, I learned: EMF = – d (PHI) /dt
    PHI(uppercase) is the magnetic flux pass through the “coil” and PHI is also equal to N*phi, where phi(lower case) is the flux through individual loop. Therefore, EMF= -N d(phi)/dt

    In the VCE question, it seems they have distinguish the words “coil” and “loop”. And the question, it asked “magnetic flux through the coil” not loop. Therefore, I suggest the answer should be B instead of A.

    For me, it seems my definition of flux is slightly different from Australia although the physics concepts are the same.

    There is a typo in the suggested solution, missed the square.
