Consider the magnetic field created by a loop of current-bearing wire along a line on the axis of the loop. At the geometric center of a circular loop, the magnitude of the magnetic field goes through a
A) maximum.
B) minimum.
C) point of inflection.
D) None of the previous answers is correct.

Question

Quizplus · Accepted Answer

At the geometric center of a circular loop of current-bearing wire, the magnetic field is at its maximum due to the symmetrical distribution of the current around the loop, leading to the additive effects of the magnetic field contributions from all parts of the loop at the center.
