- (b) a plurality of cylindrical magnetic spacers disposed between said magnets to form a longitudinal rod having a size which suffices to lodge the device in the stomach of the animal and not pass to the intestines,
- (c) said spacers and said magnets having essentially the same diameter and being arranged coaxially and adjacent to each other, said magnets being arranged such that the magnetic poles of the magnets confronting each other through the spacers are of the same polarity;
- and
- (d) two end pieces, one end piece being disposed at each end of the rod, said end pieces being generally semi-circularly shaped and having a diameter essentially the same as the diameter of said cylindrical magnets and spacers.
