whats a good way to picture the vector potental A in terms of B & like what exactly is A & how does it even exist outside a torus where B & etc =0
for example its easy to see the electric potential uses the electric field E like E*ds & its quite obvious,
wheras how does A not even contain the B field
also why is A sometimes said to not even exist or is just a paper shortcut when it actualy seems to work or exist in some way. thanks
