Why induced emf is 90 degree lagging from field mmf
Answers
Explanation:
The opposition is offered at its maximum level when the angle between first and second flux is 90°. ... The opposition is offered at its maximum level when the angle between first and second flux is 90°. Therefore ,the emf produced will always lag the flux linkage(Number of turns* flux) by 90°.
Answer:
I would really feel elated if you are able to understand the way I put the reason for this.
The flux to which the emf induced lags by 90° actually causes a current flow and this current produces another flux (by basic EM theory- Any current carrying conductor has a flux field)which induces emf ,the basic behaviour of this second flux is to oppose the cause producing it( by Lenz Law) i.e. the second flux will oppose the first flux.
The opposition is offered at its maximum level when the angle between first and second flux is 90°.
Therefore ,the emf produced will always lag the flux linkage(Number of turns* flux) by 90°.
The blue curve may be considered as the primary flux and the red curve is the curve for the secondary flux or can also be considered the curve for the induced emf.
