Researchers have constructed a 30-ton sphere that spins at more than 90 mph to generate magnetic fields. The 10-ft.-dia. sphere is filled with 13.5 tons of liquid sodium to mimic the Earths liquid ...

Magnetic Field Formula: Explore the fundamental principles of magnetic fields, including their formulas, properties, and diverse applications. Learn how magnetic fields influence everyday life and ...

DR. O. HEAVISIDE has investigated (NATURE, April 19) the slow motion of a charged conducting sphere through a uniform electric field, in a direction parallel to the electric force of the field ...

New research shows they’re affected by magnetic fields, ... As physicists have researched sound both inside and outside the range of human hearing, interesting properties have been discovered.

Our magnetic field exists today thanks to swirling liquid nickel and iron in Earth's outer core some 1,800 miles beneath the surface. The swirl generates an electrical current that powers the field.

Today, a professor at the University of Maryland is trying to build a working model of how the magnetic field inside the earth works. Tell us about Dan Lathrop and his "self-sustaining dynamo." ...

Around 3,000km below our feet — 270 times further down than the deepest part of the ocean — is the start of the Earth’s core, a liquid sphere of mostly molten iron and nickel.

But external magnetic fields would be able to distort the fields inside the hose. To look like a wormhole, the tube itself had to be made invisible. “We needed to make a 3D magnetic cloak to ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting ...

150,000-year history of Earth's magnetic field reveals clues about the climate when early humans were spreading out of Africa An ocean of magma formed early in Earth's history and it may still ...

People undergoing magnetic resonance imaging (MRI) scans must remain within the coils of the scanner’s electromagnet. Otherwise, the patient isn’t in a magnetic field uniform enough to give a ...
