( 5 marks) Consider the 3 figures below A, B and C. (a) In Fig. (A). The current $I$ through a wire is up, and the force $\vec{F}$ is left. What direction is the magnetic field $\vec{B}$ ? (b) Fig. (B). What is the direction of the velocity $\vec{v}$ of a positive charge here? (c) Fig. (C). A negative charge travels right, and $\vec{B}$ is into page. What direction is the Force $\vec{F}$ ? (a) (b) (c)
