Day 131: Moving Charge in a Magnetic Field

AP Physics C: Intro to Magnetic force on moving charge (shown without sound):

Also played with VPython program showing charged particle moving in B-Field:


  • What determines the force on the charge?
    • changing B (magnitude, direction, parallel, perpendicular)
    • changing q (magnitude, sign)
    • changing v (magnitude, direction)
  • Cross product & Right Hand Rule to determine direction of force.

The VPython program (and others) are available on the Matter and Interactions website page E&M Lecture Demo Programs.
