The Cow Magnet is an edgeless zylinder, about 3-4cm in diameter and about 10-15cm long . It consits of two parts: (i) the magnet itself whitch is about 1-1.5 cm in diameter - the axis of the cow-magnet (ii)a framed plastic-coat. To get the cow swallow it, one uses an edgeless plastic or slightly flexible metal rod whollowed on one end to take up the Cow Magnet exactly. On the other end of the rod there is a plunger. Via the mouth of the cow the whollowed end is placed at the throat and the plunger pokes the magnet into the oesophagus. This way the cow is forced to swallow the Cow Magnet. Functions and applications are well described in the articles preceeding. Best greetings Anton J.
