Magnetism Essay

Human civilisation has dealt with magnetism for millennia, earliest evidence dating as far back as 1000 BC where the ancient Chinese civilisation discovered a naturally occurring magnetic ore, magnetite. This ore, commonly known as lodestone was used by the ancient Chinese as a geomagnetic compass, however, no one really knew what magnetism was at the time. For centuries on, we have had basic knowledge regarding electricity based upon static electricity found from rubbing amber and fur. However,

Upon the first discovery of electricity, the subjects of electricity and magnetism would go on to revolutionize life as we know it. With the rudimentary work completed by the leaders within the field, such as Benjamin Franklin or Nikola Tesla, these brilliant scientists laid the foundation that would go on to become arguably one of the most important aspects of our forever-changed society. Although we have learned to incorporate electricity, it has many uses within our lives. Electric energy is at

Levitating is not only for magicians, but for magnets too. Scientist have been using magnetism to create levitation for years. Recently, they have advanced their technology and expanded their knowledge about magnetism and levitation and conformed them to be used in everyday life. Magnetic levitation can be broken down into so many different topics such as magnetism and levitation, but there is a much deeper meaning to magnetic levitation. A magnet is an object that has a magnetic field. It can

Adam Dadulak LA124 Magnets: Magneto’s Revenge Magnetism Magnetism is a class of physical phenomena mediated by magnetic fields. All materials are in some way influenced by a magnetic field. The force between any two charged particles depends on the magnitude of the charge on each and the distance that separates them. In addition to electrical forces, there is a force due to the motion of the charged particles known as the magnetic force. Magnetic Poles Magnetic forces exert on one another similarly

Generally magnetite, Fe3O4, is most commonly used although other materials, such as MnFe2O4 and CoFe2O4 are possible. A usable magnetite can be easily made by the reaction of Iron(II) and Iron(III) ions in a basic solution such as ammonia. Magnetite?s magnetism is related to its inverse spinel structure that is easily which is present above 120 K. The structure consists of a

Being a metal, plutonium should technically be magnetic, however, all evidence and studies up to this point in time have shown the exact opposite. A team at Los Alamos National Laboratory (https://www.lanl.gov/) have found where this missing magnetism actually it. But there are plenty of metals that don’t stick to a magnet. Yes, that’s true, though ‘magnetic’ in this sense means something a little different. Metals that don’t stick to magnets are known as ‘non-ferrous metals’. Some of these metals

Abstract: The task of this assignment is to evaluate the of a coil gun using the variables of number of rapes of coil and the distance the projectile will travel. Then will evaluate and investigate the physics behind the gun. Aim: The purpose of this investigation the efficiency of a coil gun using the relationship between the number of coils and the distance the projectile travelled. Hypothesis: In this investigation there is a relationship between the number of coils and the distance the projectile

Music Flies: The process of how magnets repel each other causing levitation Magnets have always been a mystery. The curiosity of how the magnets attract or repel one another has always been a topic that scientists are deeply interested in discovering. Over the years, many scientists have made huge strides in the scientific world as to how magnets work. Magnets that repel one another can cause one of the magnets to levitate over the other. A magnet is an object with a magnetic field. A magnet

Residual Magnetism in Permanent Lifting Magnets I Introduction In response to a safety incident which occurred at the Campina plant on January 9, 2015 as a result of residual magnetism, research on the issue of remanence in lifting magnets was necessary. By sharing this study on residual magnetism, we will bring understanding of and awareness to the risks involved with lifting magnets, so that they can be mitigated and further injury prevented throughout the company. II Background An operator
