How did mine sweepers work in ww2?
Minesweepers also have an electrical system used to reduce their magnetic field, in order to avoid detonating magnetic mines. Other devices were used to create a field strong enough to detonate mines at a distance. Against acoustic mines, minesweepers used a sound-making machine made of a hammer hitting on a case.
How do modern minesweepers work?
The modern minesweeper is designed to reduce the chances of it detonating mines itself; it is soundproofed to reduce its acoustic signature and often constructed using wood, fiberglass or non-ferrous metal, or is degaussed to reduce its magnetic signature.
How do minesweepers sweep mines?
By ship. A sweep is either a contact sweep, a wire dragged through the water by one or two ships to cut the mooring wire of floating mines, or a distance sweep that mimics a ship to detonate the mines. The sweeps are dragged by minesweepers, either purpose-built military ships or converted trawlers.

Why are minesweepers made of wood?
Minesweepers. To be lightweight and provide greater speed Torpedo Boats were made of wood . Minesweepers, however, required wood to avoid the magnetic detonators on many of the naval mines at the time. The United States built 481 of this sturdy craft, designated YMS.
How do mines float?
The explosive and detonating mechanism is contained in a buoyant metal or plastic shell. The depth below the surface at which the mine floats can be set so that only deep draft vessels such as aircraft carriers, battleships or large cargo ships are at risk, saving the mine from being used on a less valuable target.
