There were many types of mines used in World War Two. Magnetic mines were some of them.
No warships were sunk; some support vessels were sunk by mines.
Samuel Colt was one of the better known weapons experts in the 1840's in America. He conducted experiments with underwater mine explosives. His underwater weapons were detonated by electrical impulses sent from shore with an insulated cable. On at least five separate tests he was able to destroy vessels he used for experiments. In one test he was able to destroy a "test" vessel of five hundred tons. Later on he was able to detonate mines via cable from as faraway as forty miles. He ended his experiments by the mid 1840's.
Copper mines in Mexico are not as paramount as mines of other minerals like silver or gold. Nonetheless, Mexico is the 18th largest producer of copper in the world, with several mines throughout its territory.
The same thing it does in any other war: find and destroy naval mines so they won't find and destroy warships. The enemy really doesn't like you doing this, so minesweeper crews get attacked frequently.
In Vietnam the search-and-destroy missions were when US soldiers went into the heart of the Vietnamese countryside searching for the Vietcong, destroying any enemy strongholds, supplies or weapons they found. They often had to avoid traps set up by the Vietcong, such as mines under steps and leaves.
When a ship was directly above one of these mines, the weak magnetic radiation around the ship would reach the mine causing it to explode directly under the ship.

The Zimmerit coating for tanks was originally used by the Germans during WWII as a coating to pretect their Armored Fighting Vehicles and Self Propelled Guns from magnetic mines. While Zimmerit itself has no anti-magnetic properties, the ridged texture that it was given in the factories prevented the magnetic mines from making direct contact with the surface of the tank. At which point, the tanks own movement and vibrations would cause the mine to fall off. It was a wonderful idea, but the Germans were the only country to actually employ the use of magnetic mines during the war.
