10.1 The Lorentz force law - MIT
Scott Hughes10 March 2005 Massachusetts Institute of TechnologyDepartment of Spring 2004 Lecture 10: magnetic force ; magnetic fields; Ampere s The Lorentz force lawUntil now, we have been concerned with electrostatics the forces generated by and actingupon charges at rest. We now begin to consider how things changewhen charges are simple apparatus demonstrates that something wierd happens when charges are inmotion: If we run currents next to one another in parallel, wefind that they areattractedwhen the currents run in the same direction; they arerepulsedwhen the currents run inopposite directions.
