ampere-turn
ampere-turn — 名詞
1. a unit used in electrical engineering to measure the magnetic force created when
安匝
磁動勢的計量單位
a unit used in electrical engineering to measure the magnetic force created when a single loop of wire carries one ampere of current
In class, Rin calculated that one loop carrying one ampere makes one ampere-turn.
在課堂上，Rin 算出一圈導線通過一安培電流會形成一安匝。
formula idea: one turn x one ampere
The repair guide says this relay needs fifty ampere-turns before the switch closes.
維修手冊說，這個繼電器至少需要五十安匝，開關才會閉合。
pattern: need + number + ampere-turns
Andrés noted 200 ampere-turns for the small lifting magnet.
Andrés 為那個小型起重磁鐵記下了 200 安匝。
Jessica doubled the coil turns to get more ampere-turns without raising the current.
Jessica 把線圈圈數加倍，好在不提高電流的情況下得到更多安匝。
Engineers choose the wire size after checking the door lock's required ampere-turns.
工程師在確認門鎖所需的安匝後，才決定導線尺寸。
文法句型
[number] + ampere-turn(s)
need / produce / create + [number] + ampere-turn(s)
用法筆記
This unit is mostly used in technical writing about coils, relays, and electromagnets. It nearly always appears with a number, and the value rises if you increase either the current or the number of coil turns.
