Magnetic fields exert forces on charges or currents that are perpendicular to the field lines, while charges moving parallel or anti-parallel experience no force. This phenomenon is rooted in the fundamental principles of electromagnetism, specifically described by the Lorentz force law. The orientation of the magnetic field created by a moving charge interacts with the external magnetic field, influencing the force experienced by the charge.
PREREQUISITESPhysics students, educators, and professionals in electromagnetism or electrical engineering will benefit from this discussion, particularly those interested in the behavior of charges in magnetic fields.
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.lizdrotos said:Why do magnetic fields only apply force to charges/currents that are perpendicular to the field?
Such a "why" question cannot usually be answered.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?
