Revered members,

Homework Equations
AB and CD are two straight very long parallel conductors placed in air at a distance a. They carry currents I1 and I2 respectively. B1 and B2 are magnetic inductions.
In the book its been mentioned the direction of force can be found out using Fleming's left hand rule.
The Attempt at a Solution
Flemings left hand rule states, stretch the first three fingers of left hand mutually perpendicular to each other, if forefinger represents the direction of magnetic field, middle finger represents the direction of current, then the thumb represents the direction of force.
I have attempted to find the direction of force using this rule. In my attachment i have drawn two right angled line, on the left of AB and to the right of CD. MF represents middle finger and FF represents forefinger.
so my left hand's middle finger is pointing to the direction of current, so according to the left hand rule, the force should point upwards, that is upwards where the two lines meet that is where forefinger line and middle finger line intersect . But here the direction of force is different, also direction of magnetic field is different.
So where do i go wrong? Please let me know members
Thanks in advance
