'LE B P L (V) Hall Effect: A constant magnetic field of magnitude B points out of the paper. There is a steady flow of horizontal current flowing from left to right in the x direction. A. (5 points) What direction is the velocity vector for the electrons in the material given the direction of the current I. B. (10 points) What direction is the force on the electrons acting due to the magnetic field? C. (10 points) The voltage read by the voltmeter between points P1 and P2 is 3.5x10-6 V (due to accumulation of charge). If the magnetic field is 0.4 T and the distance b is 1.5mm. What is the velocity of the electrons in the material? (Hint: force due to electric field and magnetic field must be equal; V=Eb).
