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

yeah i'll take it easy and dont judge people so quicky and then we will all get alone fine, I have no problem with being wrong but i resent being told to stfu

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.

no need for the N either

oh yeah !!!
why didnt i see that..
thx a lot man !
been cracking my head for the past 10 mins actually

and yes ive used the wrong formula
argh..hehehe...sorry all

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!

Stop Multiplying By N It's Not Needed!!!!

Thank, i see. I don't think that question was worded properly!
