If i have two cylindrical shells one inside the other , Like a pop can inside a larger pop can.
And let's say they are infinitely long . And on the inner one i have a surface current and on the outer one i also have a surface current but in the opposite direction. The B field in between the 2 cans just depends on the current from the inner can. Is the reason that the current does not matter from the outer can because the field cancels itself , Can we use the same argument from a guass surface , Like the E field inside a spherical shell with charge Q.
The E field is zero . Sorry If my writing seems choppy.
