Homework Statement
an infinite slab is centered on the xy plane. the top of the slap is at z=a/2, the bottom of the slab is at z= -a/2. A volume current (J) is set up within the slab. find B everywhere
J = k (1 - z^2/a^2) [itex]\hat{y}[/itex]
Homework Equations
amperes law
The Attempt at a Solution
the only thing I am confused about is finding B inside the slab.
I was going to set up my amperian loop as a rectangle, which is oriented perpendicular to the volume current.
The rectangle would extend a distance z above and below z=0 (z still inside the slab)
however my textbook mentions B is discontinious at a surface current, so i am uncertain if my amperian loop takes that into account.
But given the stuff we have learned so far, I am very confident that we are supposed to apply amperes law to this situation.
Can anyone explain if you can still apply amperes law for points inside a volume current?
