Induced magnetic field

  1. Oct 13, 2013 #1
    If the induced emf = -d(phi)/dt that is the rate at which the flux through a body is increasing, can the induced current ever be more than the actual current so as to oppose the field created?
    Because the rate at which the flux through a body is increasing can be greater than the flux it already holds (what i mean to say is d(phi)/dt > phi). So is it possible that the induced emf be more than the actual emf creating the current?

    Also, do Induced emf actually create current flowing in the opposite direction of the current that is causing the magnetic field? (Not the the induced magnetic field)
