Closed metallic structures, such as Faraday cages, are structures that block electromagnetic signals and prevent conventional ...

In the nanometer range (billionth of a meter), interactions occur between light and matter that do not happen on larger ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle ...

Contrary to what many believe, the noise of a clap is largely not the sound of two hands smashing into each another, the ...

In this work, the coalescence of multiple liquid marbles was achieved via acoustic levitation ... Liquid marbles do not coalesce under vertical vibration (Movie 5). (ZIP) Noncoalescence of two liquid ...

SRMs can show different vibration and acoustic noise behavior due to the differences in the designs, e.g. thinner rotor back iron to achieve smaller inertia, and longer stator pole height to improve ...

Abstract: This paper focuses on the electromagnetic vibration and its reduction in PM brush dc motors. First, the air gap flux density distribution and the radial force density distribution are ...
