In the section of the book related to transformers (http://www.allaboutcircuits.com/tex...chpt-9/mutual-inductance-and-basic-operation/), in the next image
It's not clear to me if the plotted voltage is the source voltage or the induced for the flux one (which neutralize the source voltage). I think that it's the induced one, but the footnote says "Magnetic flux lags applied voltage by 90º", which sounds like source voltage. But, if it's the source voltage, how the induced voltage in the secondary coil could have the same phase and magnitude than this? I would expect same magnitude (1:1 transformer) but opposite phase, right?
Excellent resource are you doing here, by the way. Thanks a lot for it.
