a rectangular loopand a circular loop are moving out of a uniform m,agnetic field with a constant velocity. in which loop do you expect the induced emf to be comstant during the passage out of the field and why? the field region is normal to the loops.

Expert Answer
The emf induced is directly proportional to the rate of change of magnetic flux.
Since magnetic flux is product of area and the magnetic field through it.
Since for a rectangular moving with a constant velocity, the rate of change of area will be a constant thus emf will be constant in case of a rectangular coil
