| + | $9.4.5.$ [Insert the problem statement] | ||
| + | |||
| + | ### Solution | ||
| + | |||
| + | Obviously, the divergence of the field in the lower part of the space is zero, therefore it is also zero at the border, therefore: | ||
| + | $$B_{\perp_{up}} = B_{\perp_{down}} = 0$$ | ||
| + | Since there is a field from above, it is exactly parallel to the border. | ||
