Free Charged Particle in a Magnetic Field MCQs with Answers
62 Charged Particle in a Magnetic Field MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
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.

Explanation: A moving charged particle is surrounded by three fields:Electric Field: This field arises due to the charge of the particle itself and…
Correct answer: 3 fields62. A proton is projected with a uniform velocity 'v' along the axis of a current carrying solenoid.
- A. The proton will be accelerated along the axis.
- B. The proton path will be circular about the axis.
- C. The proton moves along a helical path.
- D. The proton will continue to move with velocity 'v' along the axis.
Explanation: The proton is traveling in the same direction as the solenoid's axis. Because the magnetic field inside the solenoid is homogenous and…
Correct answer: The proton will continue to move with velocity 'v' along the axis.
