Abstract
A projectile is provided having contained therein a passive electromagnetically responsive device such as a tuned inductive-capacitive circuit. The circuit is preferably detected by stimulating oscillations at the resonant frequency of the circuit by a pulsed electromagnetic field. The projectiles are desirably used to enable remote tagging and detection and/or identification of objects including livestock.
