In electromagnetism, Ørsted's law, also spelled Oersted's law, is the physical law stating that an electric current induces a magnetic field. [ 2 ] This was discovered on 21 April 1820 by Danish physicist Hans Christian Ørsted (1777–1851), [ 3 ] [ 4 ] when he noticed that the needle of a compass next to a wire carrying current turned so ...
English: Experiment showing the Oersted's law. This demonstrates that around conductor where current flows, a magnetic field is created, as shown by the movement of the needle. Prepared, performed and explained by Prof. Oliver Zajkov, Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Hans Christian Ørsted (/ ˈ ɜːr s t ɛ d /; [5] Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; anglicized as Oersted; [note 1] 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields. This phenomenon is known as Oersted's law. He also discovered aluminium, a ...
Descriptions of many of the experiments and discoveries of these early electrical scientists may be found in the scientific publications of the time, notably the Philosophical Transactions, Philosophical Magazine, Cambridge Mathematical Journal, Young's Natural Philosophy, Priestley's History of Electricity, Franklin's Experiments and ...
In addition to known ancient Greeks' observations of the electrical properties of rubbed amber, he experimented with a needle balanced on a pivot, and found that the needle was non-directionally affected by many materials such as alum, arsenic, hard resin, jet, glass, gum-mastic, mica, rock-salt, sealing wax, slags, sulfur, and precious stones ...
The oersted (/ ˈ ɜːr s t ɛ d /,; [1] symbol Oe) is the coherent derived unit of the auxiliary magnetic field H in the centimetre–gram–second system of units (CGS). [2] It is equivalent to 1 dyne per maxwell .
The spacecraft was launched, on 23 February 1999 at 10:29:55 UTC, by a Delta II rocket, from the Vandenberg Air Force Base SLC-2W pad, as an auxiliary payload (primary payload was ARGOS and another auxiliary payload was SUNSAT; the auxiliary payload satellites were launched free of charge) into a near-Sun synchronous elliptical polar orbit, it had a perigee of 630 kilometres (390 mi), an ...
Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as Galileo's experiments, to more complicated ones, such as the Large Hadron ...
