Two long parallel wires placed side-by-side on a horizontal table carry identical current straight toward you. From your point of view, the magnetic field at a point exactly between the two wires
A) is zero.
B) points away from you.
C) points toward you.
D) points downward.
E) points upward.

Question

Quizplus · Accepted Answer

The magnetic fields created by the currents in the two wires at a point exactly between them will be equal in magnitude but opposite in direction, causing them to cancel each other out. This results in a net magnetic field of zero at that point.
