WebNov 7, 2016 · Current density is: j = I S. In the case of sphere the surface through which current if flowing is a function of x which means that the current density is also function of x. I think the current density for this problem is then: j(x) = I π ∗ (R2 − x2). This solution however gives singularities at j(R) and j( − R) so I am a bit sceptical.
