Magnetic Flux and Flux Linkage

An introduction to magnetic flux and flux linkage

[@dominicestebanrice7460]

Concise yet comprehensive. Excellent. Thank you!

[@angelsscroll]

Thank you sir! It was really helpful to understand the PI, N and the linkage... I thought that the PI is the total flux of any N turns of coils... The linkage is the total flux... Thank you!!

@ 1:51 to calculate magnetic flux linkage is simply multiply magnetic flux with number or turn. my question is, does the bigger winding wire have a higher magnetic flux? eg. if we use bigger wire so we can reduced the number of turn? just like what we've seen in electric motor with a hairpin winding.

[@harshdev9312]

bigger windings then more flux so less no of windings needed

Thank you Sir Love from India 🇮🇳

i didn't understand the term "flux linkage" now its crytal clear

[@lifeasagamer7018]

why did u divide the area by 4?

[@nawfaljafri]

if im right, i think its because area = pi*r^2 but we have distance so area = pi*(d/2)^2 = [pi*(d^2)]/2^2 = [pi*(d^2)] /4 if it seems confusing on text, just the numbers I wrote but without the awkward * and ^ and 'division but in one line' going on and it'll make sense

[@chandranibharay416]

For magnetic field linkage the symbol is Psi (ψ).

[@Brono25]

In electrical engineering I've only seen it represented as lambda

[@chandranibharay416]

@@Brono25 I have also studied Electrical Engineering.You can use both Lambda and Psi though. No issues

[@gauthamworld]

by your definition of flux linkage, the flux linkage of a coil with N number of turns will be the same irrespective of whether the turns are wound on a ferrmomagnetic solid core or around a hollow core.. .is that true? I guess if the core material is changing, then flux density will be different based on the core, and so flux linkage may be different?

[@harshdev9312]

yes precisely thats the answer to your question

[@mooodlemip4779]

My textbook uses sin instead of cos. How do I know which one to use and when?

[@JosephBidenator]

the cos is used when the area and the magnetic field lines are perpendicular to each other, and we take the normal to the area, and we compare the normal line of the area to the magnetic field lines.
