Re: [Phys-l] current vector

Gang,

I don't know if this helps, but there is a close analogy between fluid
flow and current.

____________________________
current density is to current

as

momentum density is to momentum

I don't think anyone has trouble thinking of momentum in fluid flow as
being a vector;
N'est pas?
