Diamagnetism of helium

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 magnetic field. … 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 … 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.
