When a charged particle enters the magnetic field parallel, it will:
Correct answer: C. Move straight
- A. Deflect towards North
- B. Deflect towards South
- C. Move straight
- D. Move in circular path
Explanation
If the particle is moving along the magnetic field, F=0. Hence the particle continues to move along the incident direction, in a straight line.

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.
