…Magnets with strong magnetic force cannot be used due to weight restrictions, so they have low sensitivity and poor vibration resistance, and are rarely used today. When demand arose for highly sensitive compasses using strong magnets, the liquid compass was invented, in which the entire compass card is submerged in liquid, and the resulting buoyancy reduces the load on the bearings. Currently, liquid compasses are used on ships and aircraft. … *Some of the terminology that refers to "liquid compass" is listed below.

…磁力の強い磁石は重さの制限から使えないので感度が弱く,また耐振性に劣るために現在ではほとんど使われていない。強い磁石を使用した感度の高いコンパスが要求されるようになって,コンパスカード全体を液体中に沈めて,その浮力によって軸受にかかる荷重を軽くする液体式コンパスが考案された。現在,船舶および航空機用には液体式が使用されている。… ※「液体式コンパス」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
