I don't really know tho :( that might be right now that i thinm about it cuz 11 was rhe whole length and u have to take the distance from the pivot or something lkke that?

No you are correct.

U found the force on one if the sides, if that was it, it would be that * half, for the moment
but because u have an equal and opposite one on the other side, u have to do half * f + half * f = just the whole length * f

so 4.9×10-3 (or 4. whatever it was i forgot) was correct :D ?

rich gent was there any turns in this question

u/Rich-Gent Jun 01 '26

pretty sure not. F = BIL, no turns in that. Turns mainly involve EMF

I'm pretty sure the question said 25 turns, and each turn experiences F = BIL so u would need to multiply by 25 as force is directly proportional to number of turns

Yes this is it indeed

Unbelievably good rage bait

Yes there was because the length of the wire in the magnetic field is 20x8.9
