Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft ...

Magnets and superconductors go together like oil and water—or so scientists have thought. But a new finding by MIT physicists ...

During the Laschamps excursion, Earth’s magnetic field weakened to just 10% of its current strength ... At its peak around 40,977 years ago, Earth’s protective magnetic bubble shrank ...

This period, called the Laschamps excursion, lasted around 2,000 years. The strength of Earth’s magnetic field dropped to just 10% of its current level, while the magnetic poles wandered far ...

Though you might think that compasses will always point towards the geographic north pole, the magnetic and geographic poles do not always align. As well as a few temporary reversals, the Earth's ...

Was your prediction correct? What's Going On Any moving electric charge creates a magnetic field around it. A loop of wire with a current creates a magnetic field through the loop. You can increase ...

The magnetic field around a straight wire is circular and follows the right-hand rule. When an electric current flows through the wire, it generates a magnetic field concentrically surrounding the ...

They found that the older samples recorded a magnetic field of similar strength to today’s, but the younger samples suggested that the magnetic field at that time was just 3% of its current ...

Researchers show that using magnetic fields can boost electrocatalysis for ... forces can stir and enhance the movement of reactants around the catalyst. This process, akin to creating miniature ...

But when the magnetic field around the nest entrance was disturbed, ant apprentices couldn’t figure out where to look, often gazing in random directions, researchers report in the Feb. 20 ...

WASHINGTON, March 27 (Reuters) - Astronomers on Wednesday announced that they have detected a strong and organized magnetic field twisted in a spiral pattern around the Milky Way's supermassive ...
