hey great example exam thank you! for question 28 b would a zero force not be able to be established if the current of the two wires where acting in opposite directions? so a 0 is dependent on the current in the wires, not magnitude but direction??

Reasonably sure if that if the currents were acting in opposite directions, R would need to be placed outside the two wires (not in between!) - as one wire would attract it while the other would push it away; it's entirely possible to establish a zero force if the wires are acting in opposite directions. Not quite sure what the last part of your question means though

Hope this helps

Hi all,
As with the last 2 comments; I have decided to withdraw the exam publicly, for reasons I won't go into.

However, this doesn't mean I won't continue to distribute it. If you wish to access the exam, please send me a DM; and I'll happily help you out
