Since electrical appliances became a very important in people’s life, scientists have studied the effects of magnetic fields on human health. In a study of magnetic fields and cancer, “Animal and Cellular Evidence,”[1]. Bo Holmberg compares many studies that apply magnetic fields on mice and rats and he reports the effect of magnetic fields on skin, liver, harmonies, and DNA. He said that studies on animals were effective in proving the extent of exposure from magnetic fields enough to cause…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

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…

nexploded ordnance presents problems to workers and the general public as these explosive devices have been left behind from world wars and other conflicts. Over time these devices have been overlain by sediment at which point they have been buried to where they pose certain dangers to the public, and workers that are contracted for infrastructure projects. There is estimated to be around 15 million acres in unexploded ordnance in the U.S. alone. Geophysicists use Magnetics in order to locate…

US Department of Education defines Magnet schools as public or charter schools that contain a specialized curriculum (2014). These curricula can vary from subjects such as science like the Bronx School of Science, or flight training at Rancho High School Academy of flight. Both programs qualify as magnet schools, however, the Bronx school is a magnet school within itself. Most programs exist within schools that provide a normal high school. These programs are more plentiful as they do not…

Mosquito Magnet Trap Placement Mosquito traps have proven that they can be effective at eliminating most mosquitoes as well as other flying insects. However, that does not mean that everyone who purchases a mosquito trap is 100% satisfied with the way it performs. In most cases, their issues could be solved if they simply take a look at where their trap is located. In order to have the trap work as well as it can, you need to make sure you understand the right Mosquito Magnet trap placement. Why…

The focus of this paper is how when a hospital obtains Magnet status it drives many positive changes in healthcare institutions. When hospitals are considered Magnet hospitals that is very attractive to nurses and companies, it makes them want to be a part of the institution. The purpose of this paper is to show how Magnet status drives healthcare change in institutions. Overview of the Magnet Designation The Magnet program idea was first brought about by nurse researchers in 1980 who wanted…

The Magnet Recognition Program is a voluntary certification program of nursing excellence and high quality patient’s care for hospitals and healthcare organizations, it is accredited by the American Nurses Credentialing Center or the ANCC (ANCC, 2008). Many research data indicate that there are lowered percentages of patient mortality deaths, higher nurse retention rates, and more patient’s satisfaction in Magnet hospitals versus non-Magnet hospitals. As of 2015, only 426 or approximately 8% of…

Magnets are one of the fundamental items in physics. This paper is meant to provide a general overview of magnets and their uses, as well as an in depth look into certain aspects of magnetism and how they relate to everyday life. Most images of a magnet come to mind as a tiny object used for hanging things on a refrigerator. But other applications are much more useful in our society in general. They are used in all kinds of speakers, in many computer parts including hard drives (for recording…

believe there are factors that set me off from other applicants. For instance, since 3rd grade, I have been part of our School District 54’s Magnet Program. This program is for those student who aren’t challenged enough in their regular classes and require a more rigorous academic program that is better suited to their needs. In order to qualify for the Magnet Program, it is essential that students do well on standardized tests (scores must be in the 98th percentile or higher), as well as…
