ArbCom elections are now open!
Hi, You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.

Hello, I'm DVdm. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Electromagnet— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. DVdm (talk) 19:29, 7 July 2019 (UTC)

Please do not use styles that are unusual, inappropriate or difficult to understand in articles, as you did in Joseph Henry. There is a Manual of Style, and edits should not deliberately go against it without special reason. Thank you. DVdm (talk) 19:30, 7 July 2019 (UTC)

Thanks for edit. Id like to add some information to -Electromagnet- that is more focused than my first rather sloppy attempt. It is true the use of electromagnets in telegraph was important. But I do think it makes sense to inform readers that Henry himself is credited with the first electrical product. I'll hold off editing -Joseph Henry-. The story of the blacksmiths motor [Thomas Davenport] and the circumstances of his acquisition of Henrys early version electromagnet needs more work.

*** For his experiments Professor Henry bought small quantities of the ore magnetite from New York's [***]  where magnetized iron spikes on a drum combed through powdered iron ore, the purest iron stuck to the spikes. After he sent some steel points to Henry to be more permanently magnetized with Henry's electromagnet, mine owner Allen Penfield requested from Henry an electromagnet with attached voltaic battery to be used at the mine to recharge the ore separators iron quills when needed. This was the first commercial electrical product. ***
