Simple magnetic field circular motion problem

  1. Dec 4, 2012 #1
    There's basically a beam of protons moving in the x-y plane, 30 degree from the +x-axis. The magnetic field is oriented in the +z-axis. So would the particle's motion be circular or helical?

    I say helical, because the velocity isn't completely perpendicular.
    Is this correct?

    If the velocity is not perpendicular to the field, what angle to you think it makes, and why?

    Okay, is it 90? So then it means it is circular? Since even though its 30 degrees from the x-axis, its still perpendicular to the B-field?

    Yes, it should describe a circle in the XY plane.
