Definition of galvanometer

A galvanometer is an instrument used to measure the intensity of electric currents. Its structure is based on the properties of magnetic phenomena. General description Galvanometers have a needle that, by means of a spring, is linked to the axis of rotation of a coil. This coil, in turn, is connected to the axis of rotation of a coil.

Definition of textile

Textile is a term that comes from the Latin word textĭlis. It is an adjective that refers to that which is linked to fabrics.

Definition of electromagnet

An electromagnet is an artificial magnet that has an iron core with a coil around it, through which an electric current passes. The iron in the electromagnet is soft iron: that is, without impurities. The magnetic field The magnetic field, in this case, is generated through the flow of the current. If […]

Definition of aerometer

An aerometer is a device used to measure the density of a gas, especially air. It is important not to confuse it with a hydrometer, which measures the density of a liquid. Density of gases The hydrometer is also referred to as a densimeter, a term that also refers to instruments that measure the density of liquids.

Definition of elastane

Elastane is a synthetic fiber characterized by its enormous elasticity. Also known as spandex (from the brand name Spandex) or lycra (from Lycra, another commercial name), it is a material made from polyurethane that is used, among other things, for the manufacture of clothing. Invention The invention of elastane is […]

Definition of aerodynamics

Aerodynamics is the area of ​​fluid mechanics that deals with the analysis of the movement of gases – especially air – and the interactions that these establish with the bodies that move in them. Interactions between gases and bodies In this framework, aerodynamics studies the forces that affect the bodies […]
