Square Loop Current: Vector Potential Zero w/ 2 Sides

Click For Summary
SUMMARY

The discussion centers on the vector potential of a square loop current, specifically addressing the conditions under which it can be zero. It is established that the vector potential is zero at the center of the loop, attributed to the symmetry of the current distribution. The conversation highlights that this zero vector potential condition applies specifically to the two sides of the loop that are parallel to the x-axis.

how could a current in a square loop has a vector potential be zero due to 2 sides only.

I believe the vector potential is zero in the center of loop only.
 
do you mean at the center the vector is zero inside the loop. or only for two sides that are parallel to the x axis.
