The motion of particles in a four bar Ioffee bottle has been studied. A set of normalized equations were used to follow the motion of the guiding center of particles in the Ioffee bottle. The nonrelativistic equations of motion assumed conservation of energy but did not assume an adiabatic motion. The motion tended to be an oscillation from one quadrant of the system to another with a simultaneous motion along the longitudinal axis. The majority of the reflections occurred due to the longitudinal bars of the container rather than to the end mirrors. The magnetic moment of a particular particle was calculated at equally spaced steps in time. The moment varied in magnitude by twenty percent of the average value. The variation tended to fall within an envelope which could be correlated to reflections which the particle experienced. Author
