State the correct expression for the magnitude of the force on a straight conductor of length

L

carrying current

I

placed in a uniform magnetic field

B

making an angle

\theta

with the conductor. (a)

F = I L B \cos \theta

(b)

F = I L B

(c)

F = I L B \sin \theta

(d)

F = 2 I L B \sin \theta
