A current I flows in a wire that is oriented as shown. The vector representing the magnetic field that results in a maximum force on the wire is

Question

Quizplus · Accepted Answer

The direction of the magnetic field can be found using the right-hand rule, where your thumb points in the direction of the current and your fingers point in the direction of the magnetic field. In this case, the magnetic field would be pointing into the page, perpendicular to the direction of the wire. The only answer choice that corresponds to a magnetic field pointing into the page is answer choice C.
