Problem
A rectangular conductor develops a Hall voltage that makes its top edge positive when a current flows to the right in a magnetic field directed into the page. If the direction of the magnetic field is reversed and all other conditions remain the same, what happens to the sign of the Hall voltage? Explain in one sentence.
