O QUE SIGNIFICA DIPOLE EM INGLÊS
Dipolo
Na física, existem vários tipos de dipolos: ▪ Um dipolo elétrico é uma separação de cargas positivas e negativas. O exemplo mais simples disso é um par de cargas elétricas de igual magnitude, mas um sinal oposto, separado por alguma distância. Um dipolo elétrico permanente é chamado de eletreo. ▪ Um dipolo magnético é uma circulação fechada de corrente elétrica. Um exemplo simples disso é um único loop de fio com alguma corrente constante através dele. ▪ Um dipolo atual é uma corrente de uma pia de corrente para uma fonte de corrente dentro de um meio. Os dipolos atuais são freqüentemente usados para modelar fontes neuronais de campos eletromagnéticos que podem ser medidos usando tecnologias MEG ou EEG. ▪ Um dipolo de fluxo é uma separação de uma pia e uma fonte. Em um meio altamente viscoso, um misturador de cozinha de dois batedores causa um campo de fluxo de dipolo. ▪ Um dipolo acústico é a versão oscilante do mesmo. Um exemplo simples é um falante dipolo. ▪ Qualquer escalar ou outro campo pode ter um momento de dipolo. Os dipolos podem ser caracterizados pelo seu momento dipolo, uma quantidade vetorial.
definição de dipole no dicionário inglês
A primeira definição de dipolo no dicionário é duas cargas elétricas ou pólos magnéticos que têm magnitudes iguais, mas sinais opostos e são separados por uma pequena distância. Outra definição de dipolo é uma molécula na qual o centro da carga positiva não coincide com o centro da carga negativa. Dipole também é chamado também: antena de dipolo. uma antena direta de rádio ou televisão consistindo em dois comprimentos iguais de fio ou hastes metálicas, com um fio de conexão fixado entre eles na forma de um T.
