Answer: C. The current and field directions are $53.1^\circ$ and $36.9^\circ$ north of east, so the angle between them is $16.2^\circ$ with $\sin\theta=0.28$ Thus $F=BIL\sin\theta=(0.50)(2.0)(0.50)(0.28)=0.14\ \mathrm{N}$ Fleming’s left-hand rule gives a downward force.

A: gives the correct magnitude but reverses the force direction.
B: uses $\cos\theta$ giving $0.48\ \mathrm{N}$ and reverses the force direction.
D: uses $\cos\theta$ giving $0.48\ \mathrm{N}$ but gives the correct direction.
Remember: the force depends on the component of the current direction perpendicular to the magnetic field.
