1. The problem statement, all variables and given/known data When there is a changing magnetic flux, emf is induced in the solenoid. The solenoid is made up of circular loops of wire. My first question is, since emd is induced in the solenoid, is there a site of higher voltage and another site of lower voltage? My second question is, (as provided in the picture attached), it is said that at (c), flux does not change hence there is no emf, but there is separation of charges. How is this possible? 2. Relevant equations EMF= -N ( delta phi/ delta time) 3. The attempt at a solution For my second question, when there is separation of charges, isn't there an emf?
