Run this preset for a while. The electric field is in the x-direction. What are the x- and y-components of the average velocities? (You can get a less noisy estimate from the slopes of the position graphs.) The angle between the electric field and the current direction (the negative of the direction of the drift velocity) is called the Hall angle.
What happens to the Hall angle as the magnetic field is increased? How does it depend upon the scattering time? Can you find two pairs of field and scattering time that give the SAME Hall angle?
