In these two cases , emf will be induced in different way.
for motor: current +B-field-->Force-->Coil rotate-->change of magnetic flux-->emf inducedd in the coil
for inductor , when the switch suddenly openfrom closes switch, there are a sudden change of magnetic flux ,there emf will be induced
the thing I want to ask:
why when the coil is suddenly jammed and come to stop,there will not be any induced emf in this cases??
isn't it just the case of inductor,there are a change of magnetic flux
from many to none magnetic flux ?
why?
thank you
