What answer did you get Fizzy?
JoshMosh2 argued that it was C (apparently this was the case in an independent exam) - he said that we don't use the sin30 and simply do F=3x10^-4x 3 x 0.3
So I'm extremely confused as I was under the assumption that F=3x10^-4x 3 x 0.3 x sin30
Initially, the exam had A as the answer, but after hearing what josh said, our teacher changed the answer to C. o.o

I thought of this question too LOLThat is weird indeed..
I don't know. In a case like this: View attachment 32029
the wire is always perpendicular to the magnetic field, so theta = 90 degrees.....and sin90 = 1.
So in this case F = BIL is all you would need. However, in your case, I would think that you would need to times by sin(30)..
Sorry I'm not much help
That's just wrong...LOL.Well, Josh said that the length of wire is 30cm and thus we no longer need to multiply by sin30. He further backed his argument as he said that the answer (to an identical question) in an independent paper was C
