Homework Statement
http://grephysics.net/ans/9277/54
I am confused about this. The explanation for why the induced current is clockwise is because the induced current would resist the change in magnetic flux, therefore work to increase the magnetic field. But if the current induced in the wires is in the same direction as the original current, I use the right hand rule and it seems as if the magnetic field's will work to cancel each other out.
I'm picturing two circles going around each wire in the same direction (magnetic field) and between the wires one magnetic field will be going up while the other goes down.
Where is my thinking going wrong here?
Edit:
Is it because if the current is moving in the same direction, there will be an attractive force and therefore it will fight to increase the magnetic field? I feel like this logic isn't right because everyone else seems to be deducing the fact that it is going clockwise and then use that information to decide which way the forces are pulling on each side
