The Earth's magnetic field protects
the planet from cosmic rays. Sea
mines also make use of it to
identify and destroy ships. To
prevent this, MTU is able to erase
an engine's magnetic signature.
The Earth’s magnetic field is what produces the
magnetism present in any normal engine. It is created in
the core of our planet and extends roughly 60,000
kilometers out into space. Since the poles of the magnetic
field shift by around 50 kilometers every year, there is a
divergence between the magnetic poles and the
geographical poles.
