Consider 2 dipoles separated by a distance of atleast 2 light minutes or so .
we can call the 1st dipole A .
the distance btw the opposite charges is small so the field strength is weak same for the other dipole B .
Now we increase the distance btw the charges in dipole A so the field strength increases and it travels to B.
at the exact time it reaches B we increase the distance btw the charges of the dipole B . so due to the Field which has reached B it statrs accelerating let's say in the positive x direction.
Now due to the increase distances btw the charges at B the filed generated by B starts travelling towards A .
BUT if we combine the charges at A effectively Neturalising it there won't be any charge for the field to act on .
BUT MOMENTUM is not conserved in this case cuz only b is moving and nothing is moving in the opposite direction.????????????????
