    the bit where you say i dont know anything about physics is the bit that says if you don't know what you are talking about plz stfu
    and you need to apologies because on that matter you are wrong
    theoretically, i never said you were rubbish at physics - i just said you don't know what you're talking about.

    which actually equates to the same thing
    ie, you dont know what you are talking about since you have no idea about physics
    why else would i have no idea what i am talking about?

    and for 9.9 my answer is: 3.88 x 10^-6 Wb (3.9 or 4 x 10^-6 Wb )

    just can't be bothered to type the working out, gota go bye

    find me where i said you were ' rubbish at physics ' then i'll close shush

    till next time, take it easy

    you just multiplied everything together...regardless of whether BIAN is a correct formula or whatever....length has nothing to do with this i'm sure!?
    nopes
    BIAN is a formula...and yes it does exist..
    ive read it somewhere..hopefully im right
    anyways..ill just try and figure it out

    i just found out, BAIN is actually to do with force of a motor - A is the area of the single coil, N is the number of turns etc....so yes you are right it is a formula, but it is not the correct formula for here

    yo
    one question about q9.9
    i got it all except this one
    why didnt you use

    NFlux = BIAN ??
    cause mine was
    Nflux = (2-10^-3) x (200) x (2) x (0.05x0.25)
    = 0.01Wb
    Because it says that a current of 2A produces a flux density of 2E-3.

    So you can use Flux Linkage = BAN - there's no need for the I.

    OK, thanks ppl - i was converting cm^2 to m^4 that's why i was getting all of them wrong. I managed to do all but SAQ 9.9? Have a look at my working out and see if you can spot the problem coz i cant!
