Question
What is the maximum magnitude of the force on an aluminum rod with a $0.100 \mu\textrm{C}$ charge that you pass between the poles of a 1.50 T permanent magnet at a speed of 5.00 m/s? In what direction is the force?

The magnitude of the force is $7.50 \times 10^{-7} \textrm{ N}$. It is in the direction perpendicular to both the magnetic field and the velocity.
