Earth's magnetic field

4 understanding of the Suns temperatures, in June of 2013, NASA launched the IRIS solar observatory. IRIS, short for Interface Region Imaging Spectrograph, was launched to use imaging spectrography on the Sun. NASA’s goal was to determine “how solar material moves, gathers energy, and heats up as it travels through a little-understood region in the sun 's lower atmosphere. This interface region between the Sun 's photosphere and corona powers its dynamic million-degree atmosphere and drives the solar wind.” (IRIS mission overview) This mission could help us to understand how material in the Suns corona reaches temperatures thousands of times greater than its surface. It may also explain how magnetic fields cause solar flares. All of these things will help us to understand…

In the 2008 film Wall-e, a Waste Allocation Load Lifter Earth-class is the last of its kind cleaning up garbage that has inhabited planet Earth. He is one of the robots sent out on Operation Clean Up to rid the Earth of the waste while the humans are out in space waiting for it to be safe to return home. During the film Wall-e comes across EVE (extraterrestrial vegetable evaluator), who is sent to Earth on a mission to scan for living proof in Earth. Throughout the film we observe how sociology…

Discussion The aim of this study was to investigate if age and gender are associated with children’s understanding of the earth’s structure. It was hypothesised that: older children will have a better scientific understanding of the structure of the earth compared to younger children, boys will have a better scientific understanding of the structure of the earth compared to girls, and younger children will construct different mental models of the earth compared to older children. The results of…

The 100 is a novel written by Kass Morgan. Kass Morgan studied at Brown University to achieve her Bachelor’s degree for literature and then later got her Master’s degree at Oxford. She now lives in Brooklyn, New York. The 100 is her most successful novel written and she has been awarded many things for this novel. This novel takes place around 300 years after the Earth was exposed by radiation, which made the Earth not safe to be on. In the novel, humans are known as the “Colony”. This…

estimated to be around 15 million acres in unexploded ordnance in the U.S. alone. Geophysicists use Magnetics in order to locate the unexploded ordnance to prevent accidents and damage to infrastructure as these devices may still be active. This is done via a variety of ways and applications. By mainly using magnetic waves we are able to detect certain anomalies in data to a certain…

The article Cosmic Turbulence May Spawn Monster Magnetic Fields discusses a lab experiment that aimed to investigate the mysterious and powerful properties of magnetism in space. Magnetic waves are extremely prominent in our universe, which consists of dense galaxy clusters and vast voids of space separating these clusters. While it seems obvious magnetism would be present in the various galaxy clusters, as they are active regions of space, astronomers have also discovered a very strong magnetic…

through the day. These auroras are caused by charged particles that collide with the magnetic atmosphere. At first glance the aurora looks to be light in colour but the substorm after the first glow is a lot brighter and has a much darker colour. Yusuke Ebihara is a physicist from Japan who has been studying these northern lights. He and his partner, Tanaka, used a computer to create many different sequences…

Q. Why do wire and a compass work to detect electric currents? A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is…

Chapter 1 INTRODUCTION The study of magnetohydrodynamics (MHD) draws from two well known branches of physics, electrodynamics and hydrodynamics.The basic laws of electrodynamics described in the form of Maxwell’s Equations where The hydrodynamics of a fluid is expressed in the form of conservation laws of mass, momentum and energy.The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well…
