Two concentric, coplanar, circular loops of wire of different radii carry currents in the same direction. Describe the qualitative force exerted on the inner loop by the outer loop and on the outer lop by the inner loop.

Explanation:

Ampere's correct hand rule;  

Twist the fingers of right hand along the heading of the present stream in the curl. The extended thumb shows the course of the attractive field. The flows are equal since current conveying by the circles are same heading. In this way, they are pulling in one another. In this way, the powers from the two circles will be pointed towards one another.  

Utilizing right hand rule, the power on inward circle by the external circle and on the external circle by the internal circle will be radially outwards.

Explanation:

We understand that the forces that exists between the two parallel current carrying wire is an attractive force. If the current flows in the same direction and repulsive of the current that flows in opposite direction. Therefore the forces from the two loops will point towards one another.
