Problem
The magnetic flux through a fixed conducting loop is increasing with time. What will be the nature of the magnetic field produced by the induced current in the loop?
(a) It will aid the increase in flux.
(b) It will depend only on the resistance of the loop, not on the change in flux.
(c) It will oppose the increase in flux.
(d) It will oppose the existing field irrespective of whether the flux is increasing or decreasing.
