A strong magnetic field is applied on a stationary electron, then the electron _.
Correct answer: D. Remains stationary
- A. Moves in the direction of the field
- B. Moves perpendicular to the direction of the field
- C. Moves opposite to the direction of the field
- D. Remains stationary
Explanation
A strong magnetic field is applied to a stationary electron. Then the electron remains stationary because magnetic force act on moving charge.Hence, the option C is the correct answer.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
