The phase difference between the flux linkage

Webb6 juni 2024 · Now consider what the rate of change of flux lines cut is when the coil is repositioned by 90 degrees (vertical to the picture shown). The maximum number of flux lines are passing through the coil but there are the same number of flux lines being cut slightly before and slightly after and therefore, the rate of change is actually zero.
