As we learn more about electricity, we have to talk about fields. As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating ...

An introduction to Coulomb’s Law and electric fields explained in a clear and simple way. Learn how electric charges interact, how force depends on distance, and how electric fields describe these ...

"...a personal field ... as portrayed in many science fiction movies and comic books, that is invisible to the naked eye—that will take some doing." Reading time 5 ...

This video explores the electric field of a uniformly charged disk through both analytical derivations and numerical simulations. By comparing exact solutions with computational results, we highlight ...

Quantum electrodynamics was put to the test with highly charged uranium ions To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic ...

Electrifying: a bumble-bee's tiny hairs detect electric fields. (Courtesy: G P Sutton et al.) The bumble-bee uses its distinctive yellow-and-black fuzz to sense weak electric fields. This is the ...

How piezoelectric materials are used to create a defined acoustic field. How this field, in turn, is used to develop modulate an electric field. How the combined acoustic and electric fields can ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...
