Method and device for tagging a macro-organism

摘要

In a method and apparatus for magnetizing an identification tag prior to insertion thereof into a host macro-organism, the tag is provided with a magnetic field having an orientation opposed to the magnetic field of an injection wire from which the tag has been cut. The tag and the leading end of the wire repel one another and facilitate implantation of the tag into the macro-organism by preventing withdrawal of the tag with the wire upon termination of an injection operation.
