Motors and Generators equation help!?

1. A conductor carrying 2.5A experiences a force on 0.6N when 0.4m of its length is placed in a magnetic field of intensity 2.0T.

a) Find the angle the conductor makes with the field
b) Predict the angle where the conductor will experience maximum force.
c) Predict the where the conductor will experience zero force.


2. I know we must use the equation F = BIL sin theta, I am just confused on how to re-arrange equation in order to find the angle.

You have to use the inverse sine function, or arcsin.
$$
\Rightarrow \theta=\arcsin(\frac{F}{BIL}).
$$
Your calculator probably has a button that says $\sin^{-1}$. This is the arcsin.
