Electrical field strength sensors are used to measure the strength of electrical fields. Electric fields are the product of voltage and become stronger as the voltage increases. DC electric field ...

But how would one measure the electrostatic charge of an object without touching it? Something like this field mill, which is capable of measuring electrostatic charge over a range of several ...

At a cost not far above £10 ($13.70), this was an impulse purchase driven by curiosity; these devices claim to measure both magnetic and electric fields, but what do they really measure?

Most of the coverage of this adopts the framing of talking about this as measuring the "shape" of ... charge of the electron and an applied electric field (say, from another charged particle ...

NASA has made a huge discovery: the ambipolar field, an invisible electric field around Earth that could reshape our understanding of our planet.

Listen to the full series on BBC Sounds. Charge is a property of a body which experiences a force in an electric field. Charge is measured in coulombs (C). Since electrons are so small and one ...

Pathogens have distinct electrical charges, shapes and sizes. Measuring how quickly they move through an electric field can help researchers separate different species in a sample in minutes.
