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.
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
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.
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?
