A new study published in Nature Geoscience suggests that the rotation of Earth's inner core might be slowing down. This conclusion is based on measurements of seismic waves studied by the authors at Peking University in China. This study also
From helping marine vessels avoid explosive sea mines, to assisting aircraft find their way through the Earths magnetic field, SANSA's Applied Science and Technology (AST) unit uses its unique expertise to demagnetise and calibrate. A division of SANSA, AST has
Over the past decades, rapid variations in the Earth's magnetic field have occurred, highlighting the swirling dynamo at the Earth's molten core, 3000 kilometres under the surface. Researchers at SANSA have been keeping a close eye on the latest of
When flying an aircraft it is mandatory to have a functioning magnetic compass on-board in order to navigate effectively in the event of electronic navigation device failure. Electrical systems occasionally do fail, while the Earth's magnetic field never does. Not
A steel-hulled ship is like a huge floating magnet with a large magnetic field surrounding it. The process of building a ship, within the Earth's magnetic field, develops a certain amount of permanent magnetism in the ship. When the ship
