Is magnetism important in particle interaction?

  1. Aug 27, 2009 #1
    If you fire energetic ionising particles, like electrons or protons, at a stationary target, the important interactions are ionisation, nuclear reactions and scattering.

    But if the incoming particles are travelling at high speed, will they not generate a high magnetic field? Why is such a magnetic field not important in reactions other than ionisation?

    If my assumptions are wrong, please feel free to point it out!

    In electron-electron scattering at high energy, the magnetic interaction is dominant.

    Thanks that's helpful. Sometimes I can't see the wood for the trees!
