| Title | Unpublished manuscript, 'On magneto-electric induction in liquid and gaseous conductors. Part I - Production of induced currents in electrolytes' by J A [John Ambrose] Fleming |
| Date | 1877 |
| Description | This paper contains an account of an experimental inquiry into the production of induced currents in liquids by magneto-electric induction. Faraday examined one such case of induction, in which a conducting liquid was used as a secondary circuit. He coiled round the armature of an electromagnet a rubber tube filled with dilute sulphuric acid, and found, on making and breaking the primary circuit, the induced currents generated in it, as in the case of metallic conductors; but he could not obtain any effect when brine, sulphuric acid, or other solutions were rotated in basins over a magnet, or enclosed in tubes and passed between the poles. He failed also to detect any magneto-electric current in water flowing across the earth’s lines of magnetic force. Fleming suggests that since the reason for these negative results is not at once obvious, it seemed desirable to repeat and extend them to other cases, so that, if possible, the analogy of electrolytic with solid conductors might, in respect to magneto-electric induction, be completed. In addition, the subject involves the question of the magneto-electric phenomena accompanying the flow of ocean currents and other large masses of water.
