A magnetic field parallel to the x axis with a magnitude that decreases with increasing x but does not change with y and z is impossible according to:

Quizplus · Accepted Answer

Gauss' law for magnetism states that the net magnetic flux through a closed surface is zero, implying that magnetic field lines must form closed loops. A magnetic field that decreases with increasing x without changing in y and z would imply a divergence in the field, violating this law.
