Question

The magnetic force acting on a moving charge in a magnetic field is the product of three quantities namely

• A. charge, speed, electromotive force
• B. charge, magnetic flux, magnetic flux density
• C. charge, speed, magnetic flux density
• D. charge, speed, current

Answer 1

The Correct Option is C

The magnetic force F acting on a moving charge q with velocity v in a magnetic field with magnetic flux density B is given by: 

F = qvB sin θ, where: - q is the charge, 

- v is the speed (velocity) of the charge, 

- B is the magnetic flux density, - θ is the angle between the velocity vector and the magnetic field. 

Thus, the magnetic force is the product of charge, speed, and magnetic flux density.
