    en.wikipedia.org/wiki/Vibrating-sample_magnetometer

    Relation to Physics [ edit ] The VSM relies on Faraday's law of induction , with the detection of the emf given by ε = N d d t ( B A c o s ϑ ) {\displaystyle \varepsilon =N{d \over dt}(BAcos\vartheta )} , [ 7 ] where N is the number of wire turns, A is the area, and ϑ {\displaystyle \vartheta } the angle between the normal of the coil and ...

    en.wikipedia.org/wiki/Scientific_instrument

    Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...

  6. Langmuir–Blodgett trough - Wikipedia

    en.wikipedia.org/wiki/Langmuir–Blodgett_trough

    A Langmuir–Blodgett trough (LB trough) is an item of laboratory apparatus that is used to compress monolayers of molecules on the surface of a given subphase (usually water) and to measure surface phenomena due to this compression. It can also be used to deposit single or multiple monolayers on a solid substrate.
