Thanks man. :)
Ghost Of Highbury:
Refer to the diagram attached herewith.
The orange line indicates the magnetic field. As u can see it is in a circular form, Now, here u have to use the flemming's left hand rule.
However, as the magnetic field is in circular form u have to choose one point to apply the Left hand rule. The red point marken on the line T3-T4 is that point. (Note - the red point shudve been on the wire (T3-T4), it didnt come up in the image, sry abt that)
Okay, so at that point, the magnetic field is pointing in the direction of the blue arrow (consider it as a tangent to the circle)
The brown arro indicates the current.
If u arrange ur left hand in this form u will see the movement of the wire is towards the thick rigid wire as ur thumb points towards it.
im not sure abt this, astar plz check. thanks

Dude, that was an A 1 explanation. Short and sweet, the way I like it. Thanks alot understood it completely . I'd +rep you but I have to spread the love :D
Ghost Of Highbury:
Thanks, dont worry abt the rep. Dude, one confusing thing here.
As both the wires are conducting current, both will have their magnetic field, thus u may ask, y is the magnetic field of the thicker wire taken into consideration. I think this is because the thicker wire will have less resistance, and thus more current which makes the magnetic field stronger.

i didn't get the blue aroow thing :(
