SUMMARY
The discussion centers on the relationship between magnetic fields and current flow, specifically addressing how the magnetic field (B) changes direction when passing through a conductive sheet. When the magnetic field is parallel to the sheet, it maintains equal magnitude on both sides but reverses direction by \(\frac{1}{2}\pi\). This indicates that the current (I) flows along the z-axis, which is perpendicular to the magnetic field. The orientation of the z-axis is defined relative to the plane of the sheet, suggesting that if the sheet is aligned with the computer screen, the z-axis extends into the page when the current flows leftward.
