... In (a) the magnetic field and flux are increasing. The current moves in the direction to oppose that – to decrease the magnetic field. In (b) the magnetic field and flux are decreasing. Again, the current moves in the direction to oppose that. In (c) there is no change in flux, so there is no ...
