<span class="mw-page-title-main">Induction coil</span> Type of electrical transformer

An induction coil or "spark coil" is a type of electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. To create the flux changes necessary to induce voltage in the secondary coil, the direct current in the primary coil is repeatedly interrupted by a vibrating mechanical contact called an interrupter. Invented in 1836 by the Irish-Catholic priest Nicholas Callan, with additional research by Charles Grafton Page and others, the induction coil was the first type of transformer. It was widely used in x-ray machines, spark-gap radio transmitters, arc lighting and quack medical electrotherapy devices from the 1880s to the 1920s. Today its only common use is as the ignition coils in internal combustion engines and in physics education to demonstrate induction.

<span class="mw-page-title-main">James Marsh (chemist)</span> British chemist

James Marsh was a British chemist who invented the Marsh test for detecting arsenic. Born in Kent, he was working as a labourer in Woolwich in the late 1810s and early 1820s, before joining the Royal Artillery. He was married to Mary, and had four children, two of whom died in infancy. His surviving daughters were Lavinia Bithiah (1821–1896) and Lucretia Victoria (1829–1910).
