Maximum EMF - parallel to field?

[jsmith613]

for a rotating coil in a uniform magnetic field, why is the EMF maximum when the coil is PARALLEL to the field (i.e: flux linkage = 0)

 

[truesearch]

Induced emf = rate of change of flux linkage. This is greatest when the coil s passing through the parallel position

Induced emf = rate of change of flux linkage. This is greatest when the coil s passing through the parallel position

why?

Well...it goes from zero to something in a short space of time whereas when it is at 90degrees in the same space of time it doesn't change much...not very rigorous maths
