If a charge travels through a magnetic field, it experiences a magnetic force and its velocity is perpendicular to the direction of the magnetic field. Answer the following questions about the situations given below. What is the direction of the force on a positive charge when passing through a magnetic field as indicated in the diagram? Explain how you got your answer.
