An apparatus and method detects surgical objects within the human body where the apparatus includes the surgical object utilized in surgical procedures including a marker made of a selected nonmagnetostrictive, soft magnetic material which will emit known specific selected harmonic frequencies when exposed to an alternating electromagnetic field. That emission will cause a change in the alternating electromagnetic field which can be correlated to the presence of only the selected nonmagnetostrictive, soft magnetic material.
