Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of the ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...

The team measured the electrical charge and contact areas created by water droplets spreading and contracting on a flat plate of Teflon – effectively simulating the movement of droplets over the ...

Large groups of insects can create an electrical charge in the atmosphere comparable to that of storm clouds, a new study finds. By Oliver Whang Electrical charges are everywhere, both positive and ...
