| Title | Paper, 'Preliminary note on a new magnetometer' by W Stroud |
| Creator | Stroud; W (fl 1890) |
| Date | 1890 |
| Description | Stroud writes: 'The determination of the horizontal component of the earth’s magnetic field is of great importance, not only for the purpose of magnetic surveys, but also for the determination of the absolute strength of an electrical current, a measurement frequently required, not only for scientific work of various kinds, but also for the calibration of ammeters and voltmeters, and other electrical measuring instruments. The usual method of measuring this important quantity is that of Gauss, but the method is so long and laborious, and the apparatus requisite for accurate determination so expensive, that the measurement of H is avoided whenever practicable. The writer, having devised an instrument capable of determining H with great expedition and accuracy, ventures to think that a description of the instrument may not be without interest.'
Annotations in pencil and ink. Includes one page of diagrams of the magnetometer.
