Question

A charged particle experiences magnetic force in the presence of magnetic field. Which of the following statement is correct?

• A. The particle is moving and magnetic field is perpendicular to the velocity.
• B. The particle is moving and magnetic field is parallel to velocity.
• C. The particle is stationary and magnetic field is perpendicular.
• D. The particle is stationary and magnetic field is parallel.

Answer 1

The correct option is A The particle is moving and magnetic field is perpendicular to the velocity.

When charge is placed in a magnetic field it will experience magnetic force if
1) The charge is moving as no magnetic force acts on static charge.
2)Velocity of moving charge has component perpendicular to the direction of magnetic field.
