Why do magnetic fields only apply force to charges/currents that are perpendicular to the field?

Does it have something to do with the orientation of the field created by the moving charge in relation to the field it is in?

Hello lizdrotos. Welcome to PF !
Why do magnetic fields only apply force to charges/currents that are perpendicular to the field?
Actually a magnetic does apply a force to any charge moving through it except for those moving exactly parallel, or anti-parallel to the field.
Does it have something to do with the orientation of the field created by the moving charge in relation to the field it is in?
Such a "why" question cannot usually be answered.
