Diamagnetism was first discovered when Anton Brugmans observed in 1778 that bismuth was repelled by magnetic fields. In 1845, Michael Faraday demonstrated that it was a property of matter and concluded that every material responded (in either a diamagnetic or paramagnetic way) to an applied … See more Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and See more The electrons in a material generally settle in orbitals, with effectively zero resistance and act like current loops. Thus it might be imagined that diamagnetism effects in general would be common, since any applied magnetic field would generate currents in these … See more • Media related to Diamagnetism at Wikimedia Commons • The Feynman Lectures on Physics Vol. II Ch. 34: The Magnetism of Matter See more Diamagnetism is a property of all materials, and always makes a weak contribution to the material's response to a magnetic field. … See more Curving water surfaces If a powerful magnet (such as a supermagnet) is covered with a layer of water (that is thin compared to the diameter of the … See more • Antiferromagnetism • Magnetochemistry • Moses effect • Diamagnetic inequality – Mathematical inequality relating the derivative of a function to its covariant derivative See more WebMagnetic refrigeration is a cooling technology based on the magnetocaloric effect.This technique can be used to attain extremely low temperatures, as well as the ranges used in common refrigerators..
