As global demand for sustainable energy surges, the performance ceiling of current battery technologies is increasingly tied to how efficiently ions ...

In this video, we derive the far-field electric field of a dipole in the perpendicular direction, explaining each step and the physical meaning behind the math. This breakdown helps clarify how dipole ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

Physicists are closer to finding out if the electron is a point charge or whether it has an internal distribution of charge known as an electric dipole moment. For the first time, Ed Hinds and ...

A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...
