Uterine Sound: A uterine sound is a medical instrument used in gynecology to measure the depth and length of the uterine cavity (the hollow space inside the uterus). It's typically made of stainless steel and has a long, slender, and possibly curved probe. Importantly, uterine sounds are not magnetic.
 
Magnet/Anti-Magnet: Uterine sounds are not designed to be magnetic or interact with magnets. In fact, having a magnetic component could be potentially dangerous during a medical procedure.
