Hey there, I've been searching online for a quite a decent amount of time trying to wrap my head around this concept. We've been asked to research the link between Lenz's law and DC motors, and for some reason I was given the impression that back emf was a positive to DC motors. After some online research, all that I've concluded is that back emf is produced when teh voltage is increased, which leads to the motor operating at its maximum capacity. What is the most obvious effect of Lenz's law and the way in which DC motors function? Thanks in advance.
