(1797–1878) US physicist,
who became professor of natural philosophy at Princeton in 1832. In 1829 he made an electric motor, and used insulated windings to produce a powerful electromagnet. A year later he discovered electromagnetic induction (independently of Faraday), and in 1832 he discovered self-induction (see inductance). In 1835 he invented the electric relay.
