An electron enters a magnetic field created by the wire in question 2 , determine the direction of the electron's velocity when it feels a force in the $y$-direction at a point directly above the wire. a. $-\mathrm{X}$ b. $-\mathrm{y}$ c. $-z$ d. $x$ e. $y$ f. $\mathrm{Z}$ 4. When is the torque on a current carrying loop of wire placed in a magnetic field a maximum? When a. the plane of the wire is perpendicular to the magnetic field. b. the normal or area vector is parallel to the magnetic field. c. the normal is at angle of $45^{\circ }$ to the magnetic field. d. the plane of the wire is parallel to the magnetic field. e. None of the above.
