<p>Excerpt from Researches on Diamagnetism and Magne-Crystallic Action: Including the Question of Diamagnetic PolarityBut, being a matter of fact, the question of diamagnetic polarity lies apart from these theoretic considerations. The knowledge that a magnet has two poles does not require to be prefaced by a general theory of magnetism. The essence of magnetic polarity consists in the simultaneous and in separable existence, or development, of two hostile powers which, in action, always resolve themselves into mechanical couples. Here, it may be said in passing, the key of all Faraday's difficulties - the solution of all the mechanical paradoxes which so perplexed him - is to be found. The facts of magnetic polarity can be mastered and made sure of by anybody possessing a bar magnet and a magnetic needle, or even two magnetic needles. And passing from steel magnets to bars of iron in helices through which electric currents &#64258;ow, the polarity of the iron is as much a. Matter of experimental certainty as the polarity of the magnetized steel. The question to be decided was: Do diamagnetic bodies, under magnetic in&#64258;uence, show this doubleness of action? To put the case strongly, iron 1s repelled by a magnet, as well as attracted; is bismuth attracted by a magnet, as well as repelled? That it is so is abundantly proved in the following pages. Faraday, over and over again, observed this attraction but it came to him in the disguise of magne-crystallic action, in which.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
