Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself ...

The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...

You may think you know static electricity, but its true nature has long eluded scientists. We’ve now made a huge leap towards ...

This paper considers the generation of a strong stray magnetic field using rare-earth permanent magnets. Generating a strong field in a region displaced from a magnet is considered here in the context ...

Drawing Magnetic Fields Magnetic, gravitational and electrical fields are all 2D representations of a 3D world. For this reason particular conventions are agreed upon within the physics world. When ...

Figure 1. Calculation of the mass-energy of gravitational field matter in the sphere layer from radius R to r outside the sphere with R0. The first modification value of mass-energy is Δℰ1 = r ∫ R ϵ0 ...

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...

Quantum sensors can measure various physical properties, including temperature, magnetic field and rotation, with extreme sensitivity. Bosch Research has been developing two types: quantum ...

This letter presents very simple analytical models for calculating the effectiveness of static and low frequency magnetic fields shielding by means of rotating electromagnetically thin nonmagnetic ...

In 2013, the ESA launched three Swarm satellites for a mission to help decode how Earth’s magnetic field is generated by precisely measuring the radiofrequency signals coming from the planet’s ...

Astronomers have measured the strongest magnetic field ever found in the universe. The honor goes to a powerful type of neutron star, with a surface magnetic field of over 1.6 billion Tesla.

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.
