Magnetic field

A new pathway for the stimulation of nerve cells within the body

A mechanical way to stimulate neurons.

Whoa! Astronomers watch a black hole’s corona disappear, then reappear

A colliding star may have triggered the drastic transformation.

Earth’s magnetic field changes 10 times faster than previously thought

A new study reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.

An explanation for why changes to Earth’s magnetic field are weaker over the Pacific

Like winds in the atmosphere or currents in the ocean, there are fluid motions in the liquid core of the Earth. These core flows...

New model tells the behavior of the black hole at the center of our galaxy

Milky Way hosts a supermassive black hole at its center called Sagittarius A*. A new study by the University of California - Santa Barbara, aimed...

Astronomers created the fifth state of matter in space

With the launch and operation of the Cold Atom Lab (CAL), NASA has established the sustained study and development of quantum technologies in orbit....

New ultra-sensitive magnetometer to detect magnetic fields

Almost everything around us produces a magnetic field—from our electronic gadgets to our pulsating hearts—and we can utilize those fields to pick up data...

Astronomers measured the shape of the magnetic field of the solar corona

The Sun's corona is the outermost part of the Sun's atmosphere. And he stream of energized, charged particles, primarily electrons, and protons, flowing outward...

Magnetic field controls the material’s movement around the black hole

Using observational data from the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers recently discovered that the magnetic field near our galaxy's core is so...

Physicists produced a giant entangled state of 15 trillion atoms

Quantum technologies use entanglement to outperform classical technologies, and often employ strong cooling and isolation to protect entangled entities from decoherence by random interactions.  In...

Earth’s magnetic field is gradually weakening

Earth's magnetic field is essential to life on our planet. It is a mind-boggling and dynamic force that shields us from cosmic radiation and...

Earth’s inner core is rotating, study

Temporal changes of inner-core (IC) seismic phases have been confirmed with high-quality waveform doublets. However, the nature of the temporal changes is still controversial. Geologists...
