I Magnetic Mirror/ Bottle

  1. Mar 12, 2016 #1
    Which is correct? It's almost split 50/50 when I search online. Do the particles trapped in a magnetic bottle travel around the magnetic field or around each magnetic field line? It makes more sense for them to travel around the field because the field is what changes in density not each line. Is this correct?

    You cannot count field lines. The width of their spirals depends on their momentum orthogonal to the magnetic field.
