Why voltage lags by 90° from magnetic flux?

I was not sure if I should write it here or on Physics board, but I will give a try. As I understood current (generally emf) can be generated in a system by varying magnetic flux. For example, let's ...

Will a faster rate of change of flux improve electricity generation?

From what I remember about electricity generation, a varying magnetic field is used, either the magnetic field or the coil moves to generate electricity. e = dB/dT where e = voltage induced B = ...
