-A magnetic contactor coil rated for 24 V AC is incorrectly replaced with an identical physical size coil rated for 24 V DC. How might this affect the operation of the contactor or starter?

We know for dc supply the flux is constant because of constant current.so the rate of change of flux is zero. So EMF induced in the coil zero. So coil acts as short circuit.

we know EMF induced is directly proportional to rate of change of flux.

In Lab 11 you simulated how a magnetic field can be produced by a conducting coil when powered by a DC and an AC generators. You explored the differences between the resulting magnetic fields. Consider an experimental set-up identical to what you used in the lab: a large coil connected to an AC power supply. Assume that the maximum voltage supplied by the generator stays the same but the frequency of the supplied voltage changes. As frequency changes, you measure...
