Cartesian coordinate system is shown in figure to represent the direction of magnetic field at a given point.
Magnetic field at A is due to current flow in conductor-2 and coductor 3.
In conductor-2 , current flow in -ve y direction.
If we apply right hand rule, we get magnetic fieldat A due to flow of current 3I in conductor 2 = .....................(1)
we get magnetic fieldat A due to flow of current 4I in conductor 3 = ........................(2)
By adding eqn.(1) and eqn.(2), we get net magnetic field at A =
magnetic force on conductor-2 = B×i×L , where B is magnetic field on conductor-2, i is the current flowing in conductor-2
and L is the length of conductor-2
magnetic force = B×i×L =
