The force, the magnetic force exerted by an external magnetic field on a single current carrying charge is given in the form of FB is equal to qv cross B. That’s the mathematical expression for the magnetic force acting on a moving charge in an external magnetic field. So, key point over here is this magnetic field is an external magnetic field. In other words, it is not the magnetic field generated by this moving charge.
