Hans Christian rsted (/ r s t d / UR-sted, Danish: [hns kestjn ste] (); often rendered Oersted in English; 14 August 1777 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. Outside the magnetic field, the compass needle is pointing towards North as shown below: Answer: (c) Magnetic field lines always point from North pole to South pole around the magnet. Yet at the same time, Sony is telling the CMA it fears Microsoft might entice players away from PlayStation using similar tactics. Using the Interactive The Magnetic Field Interactive is shown in the iFrame below. List the properties of magnetic field lines. Magnetic force is used to counteract the effects of the gravitational force and any other forces..

News for Hardware, software, networking, and Internet media. There is a small hot spot in the top-left corner. Scientists researching magnetic confinement fusion aim to use stellarator devices as a vessel for nuclear fusion reactions. The Bermuda Triangle, also known as the Devil's Triangle, is an urban legend focused on a loosely defined region in the western part of the North Atlantic Ocean where a number of aircraft and ships are said to have disappeared under mysterious circumstances. The idea of the area as uniquely prone to disappearances arose in the mid-20th century, but most reputable sources Hans Christian rsted (/ r s t d / UR-sted, Danish: [hns kestjn ste] (); often rendered Oersted in English; 14 August 1777 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. This would only happen if there were a magnetic field present to interfere with the needle of the compass, so he deduced that a magnetic field was generated from the electricity flowing from the battery. Use the Escape key on a keyboard (or comparable method) to The Bermuda Triangle, also known as the Devil's Triangle, is an urban legend focused on a loosely defined region in the western part of the North Atlantic Ocean where a number of aircraft and ships are said to have disappeared under mysterious circumstances. The module is a detector that measures antimatter in cosmic rays; this information is needed to understand the formation of the Universe and search for evidence of Teachers Teaching Tools Homepage. Then the unknown current is applied to the coil. But Oersted gravitated toward the field of chemistry and left the research of electricity and magnetism to others [source: Mahon]. Design an activity to demonstrate that a bar magnet has a magnetic field around it. The compass needle responds to the vector sum of the two fields, and deflects to an angle equal to the tangent of the ratio of the two fields. Solution: Magnetic field lines of a bar magnet emerge from the North Pole and terminate at the South Pole as shown in the figure below. Draw magnetic field lines around a bar magnet. This would only happen if there were a magnetic field present to interfere with the needle of the compass, so he deduced that a magnetic field was generated from the electricity flowing from the battery. That little experiment tells us that a magnetic field can penetrate through magnetic materials such as iron. Compass needle is used to draw magnetic field lines. Teachers Teaching Tools Homepage. After doing this test a few times and taking the average, the results are shown in the table below. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.Other magnetometers The idea of the area as uniquely prone to disappearances arose in the mid-20th century, but most reputable sources Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions.In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. An antenna is typically designed to radiate electromagnetic waves into the far field, with the intent being having electromagnetic field strength which falls off as 1/r instead of 1/r^2 like the magnetic field around the wire. Magnetic confinement fusion is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma.Magnetic confinement is one of two major branches of fusion energy research, along with inertial confinement fusion.The magnetic approach began in the 1940s and absorbed the majority of subsequent development. First, Oersted didnt create the first antenna just by showing that a current-carrying wire has a magnetic field. This creates a second magnetic field on the axis of the coil, perpendicular to the Earth's magnetic field. This can also be verified by a simple experiment of keeping a magnetic compass near any current-carrying wire. Thus, compass needle follows the path difference of magnetic field lines. Reporting on information technology, technology and business news. Any metal that can be magnetized can be turned into a compass.
