In this video, we explain the axial dipole electric field approximation, showing how the field behaves along the axis of a dipole and why the far-field assumption simplifies the math. Clear reasoning ...

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...

Earth has a global magnetic field that’s flinging tiny bits of our atmosphere out into space. Researcher’s from NASA’s Goddard Space Flight Center recently launched a rocket high into the sky over the ...

During the 1960s, spacecraft traveling above Earth's poles discovered a stream of particles flowing out of the Earth's poles, and theorized that there must be an unknown field driving these particles ...

A strange electric field around the Earth, long suspected to exist, has been detected for the very first time, and it is believed to cause a polar wind which launches particles into space at ...

Researchers have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known as magnetoelectrics, which offer ...
