- F = BIL sin (θ)
Hi,
Here is a multiple choice question I am stuck with and would appreciate some guidance:
The mark scheme for this paper says it is option A - 0N. I didn't get that at all. If a current carrying wire is in a magnetic field with some component perpendicular to the field then how can it be zero?! I got option B by doing
F = BIL sin (θ) where θ is the angle between B and I.
F = (0.08T x 0.5A x 0.01m) sin (30) = 2.0 x 10-4 N (to 2 sig figs)
Have I missed something?
Thanks.
