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.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
