• Attach a closely wound coil to a sensitive galvanometer (Fig. 237); naturally there is no deflection of the galvanometer needle, because there is no current in the wire. 伯莎M.克拉克. 科学通论.
• During the motion of the coil, a strong deflection of the galvanometer is observed; but the deflection ceases as soon as the coil ceases to rotate. 伯莎M.克拉克. 科学通论.
• Edison was intolerant of sham and shoddy, and nothing would satisfy him that could not stand cross-examination by microscope, test-tube, and galvanometer. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• A device for continuously indicating on a galvanometer the depths of the ocean. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• There was the Thomson reflecting mirror galvanometer and electrometer, while nearby were the standard cells by which the galvanometers were adjusted and standardized. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The galvanometer of Schweigger, 1820--the parent of the needle system. 威廉·亨利·杜利特. 世纪发明.
• Put a coil of wire over the end of rod X and passed the ends of spool through galvanometer without affecting it in any way. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The current pressure was regulated by a galvanometer. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.

• Between the poles of a strong magnet suspend a movable coil which is connected with a sensitive galvanometer (Fig. 237). 伯莎M.克拉克. 科学通论.
• This latter and the metal plate are connected in an electric circuit which includes a battery and a sensitive galvanometer. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The principle of practically all galvanometers is as follows:-- A closely wound coil of fine wire free to rotate is suspended as in Figure 233 between the poles of a strong magnet. 伯莎M.克拉克. 科学通论.
• There was the Thomson reflecting mirror galvanometer and electrometer, while nearby were the standard cells by which the galvanometers were adjusted and standardized. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• Current-measuring instruments, or galvanometers, depend for their action on the magnetic properties of current electricity. 伯莎M.克拉克. 科学通论.
