An electron is moving north in a region where magnetic field is south.The magnetic force exerted on the electron is

Correct answer: A. west

  • A. west
  • B. Up
  • C. Down
  • D. Zero

Explanation

Determining Magnetic Force on an Electron Moving Through a Magnetic FieldGiven:- Electron moving north- Magnetic field directed south#### Explanation of Options:#### Option (a) West:- **Velocity Direction:** North (opposite to the magnetic field).- **Magnetic Field Direction:** South.- Applying the right-hand rule: - Thumb in the direction of velocity (north). - Fingers in the direction of the magnetic field (south). - The force (\( \text{F} \)) is directed west, perpendicular to both north and south directions.Correct Answer:(a) West

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
