In what direction relative to a magnetic field does a charged particle move in order to experience maximum deflecting force? Minimum deflecting force?

the particle experiences maximum force when it will be moving perpendicular to magnetic field.

it experiences minimum deflecting for when its going parallel to the magnetic field.

Explanation:when a charged particle is moving

magnetic field is B which is a vector

Magnetic force on a charge is F

formula for force  F =Q.(VxB)

magnitude of the charge particle is Q

the vector multiplication of (VxB) if most significant when the charge particle is moving parallel.Very minimum when moving

velocity of the charge particle is V
