A magnetic mine is a type of naval mine that detonates when it detects a change in the magnetic field caused by a passing ship or submarine. 🚢💣 It's designed to target vessels by sensing their metallic mass. These mines are often deployed underwater and can be triggered by the iron or steel hull of a ship. They represent a stealthy and dangerous form of naval warfare. Imagine it as a hidden trap triggered by the presence of a metal object. Modern versions can be sophisticated, distinguishing between different types of vessels. It's a deadly game of cat and mouse, but underwater.
