At which angle must a charged particle be moving to experience the greatest magnetic force? a. 45 to the magnetic field b. 90 to the magnetic field c. 180 to the magnetic field d. 145 to the magnetic field

The correct answer is "90 to the magnetic field".

Explanation:

The expression for Lorentz force is as follows;

Here, q is the charge, E is the electric field, B is the magnetic field, v is the velocity, B is the magnetic field and is the angle between the speed of the particle and the magnetic field.

If the speed of the charged particle is perpendicular to the magnetic field, in this case, there is maximum magnetic force.

Put in the above expression.

Therefore, at 90 to the magnetic field, a charged particle must be moving to experience the greatest magnetic force. The correct option is (B).
