expression, noun
corkscrew rule; right-hand screw rule
A physics mnemonic: when a right-handed screw is turned clockwise, it advances forward. Used to remember the direction of magnetic fields, angular momentum, etc.
右ねじの法則を使うと、電流の向きから磁界の向きがわかる。
Using the corkscrew rule, you can determine the direction of the magnetic field from the direction of the current.
Most common modern spelling, using hiragana for ねじ.
Katakana variant for ネジ, also seen in technical contexts.
Full kanji spelling using 螺子 for 'screw'; rare and somewhat old-fashioned.
Right-hand rule: a more general term for similar mnemonics in physics, often using the right hand's orientation rather than a screw's motion.
Compound of 右 (right), ねじ (screw), and 法則 (law/rule). The phrase is a direct translation of the English 'corkscrew rule' or 'right-hand screw rule'.
