Can a static magnetic field change the momentum of a moving charged particle?

Discuss the motion of a charged particle when subjected to a uniform magnetic field when The direction of motion of charged particle is perpendicular to the magnetic field?

Discuss the motion of a charged particle when subjected to a uniform magnetic field when The direction of motion of the charged particle makes an angle with the direction of magnetic field?

What is the work done by a magnetic field on a moving charge?

A charged particle is moving away from you. If the direction of the magnetic field is clockwise, what is the charge on the particle?
