the square ofthe magnetism evoked, and was equivalent to the work used in the rotation.Foucault made a remarkable experiment by means of the apparatusrepresented in fig. 918. It consists of a powerful electromagnet fixedhorizontally on a table. Two pieces of soft iron, A and B, are in contactwith… … Fig. 918. this disc partly projects between the pieces A and B, and can be moved bymeans of a handle and a series of toothed wheels with a velocity of 150 to200 turns in a second. So long as the current does not pass through the wire of the electro-magnet, very little resistance is experienced in…
