Il a été professeur de physique au Mason Science College (qui devient plus tard l'Université de Birmingham) de 1880 jusqu'à sa mort. - Il a défini ce que l'on appelle le vecteur de Poynting qui représente la puissance par unité de surface que transporte une onde électromagnétique et la direction de ce flux d'énergie. Ce vecteur est utilisé dans le théorème de Poynting, qui établit la conservation d'énergie des champs électriques et magnétiques. Il a mesuré la constante gravitationnelle de Newton par des techniques novatrices en 1893. En 1903, il est le premier à réaliser que la radiation solaire peut attirer les petites particules vers le Soleil, effet reconnu plus tard sous le nom d'effet Poynting-Robertson. Pendant l'année 1884, il analyse les prix des bourses de commerce, notamment ceux du blé, de la soie, et du coton, à l'aide de méthodes statistiques. Des cratères sur Mars et sur la Lune ont été nommés en son honneur, de même que le bâtiment principal de physique de l'université de Birmingham et l'association du département de physique de celle-ci, la Poynting Physical Society.

On a Determination of the Mean Density of the Earth and the Gravitation Constant by means of the Common Balance. Received May 13, - Read June 4, 1891.
(London, Harrison and Sons, 1892). 4to. No wrappers as extracted from ""Philosophical Transactions"", 1891, Vol. 182 - Series A. Pp. 565-656 a. 7 lithographed plates.
First appearance of this importent paper for which Poynting was awarded the Adams Prize of Cambridge.""These days John Henry Poynting is best known for his association with the Poynting vector, which describes the flow of energy in an electromagnetic field, and little is known of his life or work. Yet in the 1890s he caught the popular imagination as the man who weighed the Earth'. His experiment, using a novel method with a common balance, was part of a heroic tradition, gained him Cambridge University's Adams Prize, and set new standards of precision. Yet in performing this experiment, Poynting seemed to step outside the traditions of late nineteenth century Cambridge University where he was educated, and it is probably significant that he was a Unitarian throughout his life.""(Isobel Falconer)..

First printing of these experiments in oder to measutre the gravitational constant.""Closely related to his investigations on the constant of gravitation is the experiments in search of a directive action of one quartz crystal on another, which, though leading to a negative result is a model of the application of refined methods to physical researc of great delicacy.""(From the motivation for receivind the Royal Medal).
