Explanation
The force acting on a charged particle moving in a magnetic field is given by the Lorentz force equation, which can be expressed as:
F=q(v×B)
Where:
- q is the charge of the particle,
- v is the velocity vector of the particle,
- B is the magnetic flux density (magnetic field strength) vector.
The cross product v×B indicates that the direction of the force is perpendicular to both the velocity and the magnetic field vectors. Thus, the correct expression for the force is F=qv×B.
