An electron is traveling horizontally toward the north in a uniform magnetic field that is directed vertically downward. In what direction does the magnetic force act on the electron? An electron is traveling horizontally toward the north in a uniform magnetic field that is directed vertically downward. In what direction does the magnetic force act on the electron? upward east south downward west north

East

Explanation:

When a charged particle moves in a region with a magnetic field, the particle experiences a force whose magnitude is given by

where

q is the charge of the particle

v is its velocity

B is the magnitude of the magnetic field

is the angle between the directions of v and B

When the particle travels perpendicular to the field, the direction of the force can be found by using the right hand rule; the index finger, the middle finger and the thumb of the right hand are placed perpendicular to each other, and:

- The index finger corresponds to the direction of the velocity

- The middle finger corresponds to the direction of the magnetic field

- The thumb gives the direction of the force (for a positive charge); for a negative charge, this direction is reversed

In this problem, we have:

- Index finger: towards the north (direction of velocity)

- Middle finger: vertically downward (magnetic field)

- So, the thumb is towards the west; however, the electron is negatively charged, so the direction of the force is towards the east.
