Maximum EMF - parallel to field?

AI Thread Summary
The discussion focuses on the phenomenon of induced electromotive force (EMF) in a rotating coil within a uniform magnetic field. EMF reaches its maximum when the coil is parallel to the magnetic field, as this position results in the greatest rate of change of magnetic flux linkage. When the coil transitions through the parallel position, the flux changes rapidly from zero to a significant value. In contrast, at a 90-degree angle, the change in flux linkage is minimal over the same time interval. This understanding highlights the relationship between coil orientation and induced EMF in electromagnetic induction.

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)
 
Physics news on Phys.org
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

of corse..thanks :)
 
Of course...js...of course
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
