The direction of magnet field

Click For Summary
SUMMARY

The discussion centers on the direction of the magnetic field generated by an infinite length of current and its relationship to Maxwell's equations. It concludes that one cannot assume the magnetic field direction of a ring on the mid-vertical plane is both the same magnitude and along the tangential direction without violating the principles of electromagnetism. Additionally, the conversation highlights that if the magnetic flux through a closed surface is zero, it contradicts the conservation of charge as outlined in Maxwell's equations.

PREREQUISITES

for a infinite length length of current, only consider a part of it, is the direction of magnet field of a ring on the mid vertical plane the same magnitude and along the tangential direction? and for a closed surface , if the flux is 0?
