Suppose that an infinite planar slab centered on the $z=0$ plane carries a uniform current flowing in the $+x$ direction. The magnetic field produced by this slab is
A) Unidirectional}
B) Axial
C) Circular
D) Radial
E) None of the above

Question

Quizplus · Accepted Answer

The magnetic field produced by a current flowing in an infinite planar slab is uniform and unidirectional, parallel to the plane of the slab, due to the symmetry of the problem and the application of Ampère's Law.
