Solving Magnetism Problem: Determine Force per Unit Length

[neelakash]

Homework Statement

A long straight conductor carries a current I.Determine force per unit length of the conductor when it is placed in a unifrom magnetic field B.

Homework Equations

The Attempt at a Solution

I got BI sin(theta) where theta is the angle between wire and the B field.
Please check if I am correct.

I believe you are correct, since:

$$F/L = \vec{I} X \vec{B} = IB\sin\theta$$
