Summary

Letter from Joseph Henry, then a professor at Princeton University and later first Secretary of the Smithsonian Institution, probably to Thomas Cooper, a professor of chemistry at South Carolina College, November 26, 1833. In the letter, Henry describes a magnet he had created, replying to Cooper's request for information. Henry was the first to construct an electromagnet formed by tightly wrapping multiple coils of an insulated conducting wire around an iron bar in 1831. Henry's magnet was capable of supporting 3300 pounds.
