In Lenz’s law of electromagnetic induction
A
A force is exerted on a current-carrying conductor in a magnetic field
B
The magnitude of the induced e.m.f. in a circuit is proportional to the rate of change of the number of lines of force linking the circuit
C
The induced current direction is always in opposition to the change causing it
D
The induced charge is constant for a fixed change of flux
