Papers of Charles Wheatstone: experimental notes on electricity

Series of outline experimental notes on aspects of electricity, including electrical induction of ebonite disks; the relationship between heat and electricity; papers entitled 'experiments with the magneto-motor', or dynamo, with comparison between different armature designs and modified reacting magnet, 1867; correspondence between Charles [Carl] William [Wilhelm] Siemens (1823-1883), electrical engineer and metallurgist, and Charles Wheatstone, on resistance in electromagnetic coils, 1867; extracts from Proceedings of the Literary and Philosophical Society, Manchester, describing the pioneering work of Charles William Siemens and Wheatstone in relation to the development of the dynamo, 1867. Also including occasional items of ephemera relating to the finances of the Wheatstone family and the assignment of rooms at King's College London with extract from letter by Sir Robert Smirke (1790-1867), architect of King's College London, 1839. With diagrams and sketches.

Papers of Charles Wheatstone: papers relating to electrical charge

Papers principally relating to electrical charge, notably including experiments to measure the charge of various materials including ebonite, ivory and rock crystal, 1872; experiments using electromagnets and specifications of components, with diagrams; description of the use of the double electrometer, magnetic gyroscope and an electromagnetic induction coil or ‘inductorium’ developed by Alfred Apps (1839-1913), optical and scientific instrument maker; notes on experiments described by the mathematician and physicist, Peter Barlow (1776-1862), in An essay on magnetic attraction (London, 1823); summaries and commentaries by Charles Wheatstone of then current explanations for magnetic induction, the distribution of magnetism in magnets and electromotive force, including perceived deficiencies in the electrodynamic theory of André-Marie Ampére (1775-1836), French physicist.

Papers of Charles Wheatstone: papers relating to magnetism

Papers relating to magnetism, comprising experimental observations and test results of electromagnets in different configurations; notes on a magnetic flywheel and governor; criticism by Charles Wheatstone of the remarks of Josiah Latimer Clark (1822-1898), electrical engineer, concerning electrical resistance; experiments to test the electrical capacities and insulating capabilities of various substances; conjectures relating to the employment of mercury as a medium for electrical conduction; draft comments intended for lectures or papers presented by Wheatstone including brief observations illustrative of Wheatstone's relationship with his academic peers and his working methods. With sketches, diagrams and tables of data
