2. Evans balance - Wikipedia

   en.wikipedia.org/wiki/Evans_balance

   An Evans balance, also known as a Johnson Matthey magnetic susceptibility balance, is a scientific instrument used to measure the magnetic susceptibility of solids and liquids. [ 1 ] [ 2 ] Magnetic susceptibility quantifies the extent to which a material becomes magnetized in an applied magnetic field .

3. Gouy balance - Wikipedia

   en.wikipedia.org/wiki/Gouy_balance

   Schematic diagram of Gouy balance. The Gouy balance, invented by the French physicist Louis Georges Gouy, is a device for measuring the magnetic susceptibility of a sample. . The Gouy balance operates on magnetic torque, by placing the sample on a horizontal arm or beam suspended by a thin fiber, and placing either a permanent magnet or electromagnet on the other end of the arm, there is a ...

4. Spin glass - Wikipedia

   en.wikipedia.org/wiki/Spin_glass

   A spin glass should not be confused with a "spin-on glass". The latter is a thin film, usually based on SiO 2, which is applied via spin coating. The term "glass" comes from an analogy between the magnetic disorder in a spin glass and the positional disorder of a conventional, chemical glass, e.g., a window glass.

5. Cavendish experiment - Wikipedia

   en.wikipedia.org/wiki/Cavendish_experiment

   The large weights can be rotated to the other side of the torsion beam (w, w), causing the beam to rotate in the opposite direction. The Cavendish experiment , performed in 1797–1798 by English scientist Henry Cavendish , was the first experiment to measure the force of gravity between masses in the laboratory [ 1 ] and the first to yield ...

6. Ampere balance - Wikipedia

   en.wikipedia.org/wiki/Ampere_balance

   A more complicated version of an ampere balance, that removes this source of inaccuracy by a calibration step, is the Kibble balance, [1] invented by Bryan Kibble in 1975. This experimental device was developed at government metrology laboratories worldwide with the goal of providing a more accurate definition of the kilogram , the world's ...

8. Faraday effect - Wikipedia

   en.wikipedia.org/wiki/Faraday_effect

   Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...
