In the Hall Effect, the electric field is in x direction and the velocity is in y direction. What is the direction of the magnetic field?

In the Hall Effect, the electric field is in x direction and the velocity is in y direction. What is the direction of the magnetic field? Correct Answer Z

The Hall Effect satisfies the Lorentz’s Force which is E=vxB So, the direction of the velocity, electric field and magnetic field should be perpendicular to each other.

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R) Assertion (A): In Gunn effect, when electric field is varied from zero to a threshold value the drift velocity decreases. Reason (R): Beyond the threshold electric field, if the electric field is increased, the drift velocity is decreased and the diode exhibits negative resistance.
