Collaboration with MagLev Aero could see XTI install magnetically levitated electric propulsion on an uncrewed aircraft for ...

Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

Opinion: In this op-ed, retired Navy Capt. John Cordle shares why he chose to retire from his position as a federal worker ...

The magnetic compass always points toward “true north,” based on the Earth’s gravitational field. It’s a relatively unchanging constant that the ship can reliably steer by.

However, MagNav depends heavily on the availability of detailed magnetic maps. “Navigation on the map without strong magnetic features is very difficult,” Jukić told New Scientist.

The result that magnetic-field detection might have evolved separately for the map and compass senses bolsters growing evidence for dual magnetoreception systems in other vertebrates 1, 3.

The World Magnetic Model, or WMM, is updated every five years and updates the position for the accuracy of GPS units while predicting the movement and shifts of the magnetic pole for the next five ...

Earth's magnetic north pole is shifting, forcing an update to the World Magnetic Model (WMM), which is used by navigation systems worldwide.

The phenomenon "may be linked to the Earth's history of magnetic pole reversals, which have occurred nearly 200 times over the past 100 million years," said Earth.com. Understanding pole shifting ...

Our technology is deeply intertwined with magnetic orientations, and any abrupt changes can cause significant turmoil. Devices like smartphones, cars, and military equipment rely on the World Magnetic ...
