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)points upward.
B)points downward.
C)points toward you.
D)points away from you.
E)is zero.

Question

Quizplus · Accepted Answer

The two wires carrying identical currents in the same direction would create magnetic fields that point in the same direction between the wires and opposite directions outside the wires. At the exact midpoint between the wires, the magnetic fields created by each wire cancel each other out, resulting in a net magnetic field of zero. Therefore, the answer is E - the magnetic field is zero.
