In a magnetic circuit, for a coil having a single turn, the flux linkage is equal to ___________.

The correct answer is option 1):(total flux)

Concept:

Faraday's laws of Electromagnetic Induction;

Statement1: There should be a change in flux linkage with the coil in order to induce emf in it.

Statement2: The magnitude of the induced emf is proportional to the rate of change of flux linkage.

Mathematically given by,

e=−\(dΨ\over dt\)

But Ψ=Nϕ ⇒ flux linkages (Wb – turns)

∴ e= \(−Ndϕ \over dt \)Where,

\(dϕ\over dt \)= Rate of changes in flux (Wb/sec)

N = Number of turns

e = induced emf in the coil (volt)

where N=1 the flux linkage is equal to total flux

The negative sign is due to Lenz’s law

Dynamically induced emf:  Examples are Motors and generators

Statistically induced emf: Examples are Transformers
