The expression for the induced e.m.f. contains a negative sign[e=-dϕ/dt]. What is the significance of the negative sign?
(a) The induced e.m.f. is produced only when the magnetic flux decreases.
(b) The induced e.m.f. opposes the change in the magnetic flux.
(c) The induced e.m.f. is opposite to the direction of the flux.
(d) None of the above.
