Action at a distance - action at a distance

Japanese: 遠隔作用 - えんかくさよう

When the force acting between objects separated by a space is transmitted directly and instantaneously without causing any change in the space between them, this action is called action at a distance. Counterpart of action at a distance. The Coulomb force in electromagnetic phenomena, the force or interaction between magnetic poles, the interaction between electric currents and magnetic poles, and the interaction between electric currents were thought to be such actions at a distance. However, it is now believed that the fundamental force in physics is the action at a distance. → Field

空間を隔てた物体間に働く力が，途中の空間には何の変化も起こさず直接瞬間的に伝わるとき，この作用を遠隔作用と呼ぶ。近接作用の対。電磁気現象におけるクーロン力，磁極間の力または相互作用，電流と磁極の相互作用，電流間の相互作用などは，このような遠隔作用だと考えられていた。しかし現在，物理学の基本的な力は近接作用であると考えられている。→場
