Using the concept of Magnetism, we got that (μ[tex]_o[/tex].q₁.q₂.v₁.v₂)/4πr² is the Force exerted by charges on each other after direction of velocity is changed.

Magnetic field is a effect around a permanent magnet or a moving charge due to which ferromagnetic objects like some of the metals get attracted, and diamagnetic substances gets repelled, when placed in the effect of magnetic field.

We know very well that if two charges are placed at some distance with each other and they are moving with certain velocity, in that case they will exert Magnetic force on each other.

We also know very well that like charges repel each other and unlike charges attract each other.

So suppose charges are of magnitude of q1,q2,vecloity is v1,and v2;

Distance between them is r.

Both charges are moving with velocity v1,and v2, in that case magnitude will remain same, only net direction of force exerted by both charge will change.

Hence, Force exerted by charges on each other after direction of velocity is changed =(μ[tex]_o[/tex].q₁.q₂.v₁.v₂)/4πr²
