The question is fairly simple but I am afraid the answer will not. I have seen many information about magnetic force between infinite parallel wires but almost nothing about finite ones.
So, let's have two finite parallel wires, each one 50cm length, in 10cm distance, both have the same current 10A of the same direction.
What force will be on each wire?
(we ignore wire begin/end parts connected to power source that can affect force result)
And how force changes if wires are shifted to half of their length, or
if we shift them by whole 50cm - will be there any force? If I understand Biot-Savart Law it seams each current carrying element is creating magnetic field that is going not just perpendicular to current direction but in all directions, so it should reach opposite wire even if wires are shifted outside each other...
