In physics, specifically electromagnetism, the Biot–Savart law (/ ˈ b iː oʊ s ə ˈ v ɑːr / or / ˈ b j oʊ s ə ˈ v ɑːr /) [1] is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current.
Jean-Baptiste Biot (/ ˈ b iː oʊ, ˈ b j oʊ /; [2] French:; 21 April 1774 – 3 February 1862) was a French physicist, astronomer, and mathematician who co-discovered the Biot–Savart law of magnetostatics with Félix Savart, established the reality of meteorites, made an early balloon flight, and studied the polarization of light.
Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many ...
Laplace's law or The law of Laplace may refer to several concepts, Biot–Savart law, in electromagnetics, it describes the magnetic field set up by a steady current density. Young–Laplace equation, describing pressure difference over an interface in fluid mechanics. Rule of succession, a smoothing technique accounting for unseen data.
Jefimenko says, "...neither Maxwell's equations nor their solutions indicate an existence of causal links between electric and magnetic fields. Therefore, we must conclude that an electromagnetic field is a dual entity always having an electric and a magnetic component simultaneously created by their common sources: time-variable electric ...
Savart became a professor at Collège de France in 1820 and was the co-originator of the Biot–Savart law, along with Jean-Baptiste Biot. Together, they worked on the theory of magnetism and electrical currents. Their law was developed and published in 1820. [4] The Biot–Savart law relates magnetic fields to the currents which are their sources.
Dry January is a challenge started in 2013 to eliminate alcohol from your diet. This is what you need to know about the health benefits.
Stephen aldehyde synthesis, a named reaction in chemistry, was invented by Henry Stephen (OBE/MBE). This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl 2 ), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH 2 ] + Cl − ) with water (H 2 O).
