SPECIALIST ARTICLE Magnets and adhesives: A durable connection Ranjit Dhaliwal, Sales Manager, DELO Industrial Adhesives, Singapore Due to their special physical properties, magnets are used in many technical and electronic application areas. Especially in machine tool construction and the automotive sector – for example, in sensors and electric motors – the magnetic fluxes induced by magnets are utilized. Here, high-energy magnets, so-called permanent magnets of the rare-earth group, allow

“Field of Bull” Realism is all about showing the truth. A realist will try to defend the assumptions that their film ideas are not influenced, but are a true mirror of the actual world. We rarely notice the style in a realistic movie; they often aim for a gritty look, with the idea that if it’s too pretty, it’s false. Their films are about everyday people and everyday situations. At the opposite side of realism, we have Formalism. Formalist directors have no desire to show reality. They want to

was Forrest superior Dan communicated with Forrest through orders. Forrest did everything that Lt. Dan asked him to do. The one thing that Forrest did not do is to save Lt. Dan before he died out on the battle field. Lt. Dan believed that it was his destiny to die out on the battle field with honor. When Forrest saved him he took away what he thought was his destiny

invisible, soundless, and cannot be touched or felt. It is electromagnetic field radiation (EMF) and it is emanating from virtually every single electrical appliance, computer, electric wire, TV, radio, microwaves and especially high voltage lines (overhead and buried) which are carrying current. Electric fields are measured in units of volts per meter or V/m. Magnetic fields are measured in milli-Gauss or mG. The field is always strongest near the source and diminishes as you move away from the

Electromagnetic fields are present everywhere around the atmosphere but are not visible. Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms. The earth's magnetic field causes a compass needle to orient in a North-South direction and is used by birds and fish for navigation.[ http://www.who.int/peh-emf/about/WhatisEMF/en/]. Now we will talk briefly about the atmospheric electromagnetic fields. There is always free electricity in

Rhetorical Analysis - Sports in America James Michener author of Sports in America argues that each sport is subject to specific criteria to explain his arguments and criticisms with the commercial direction it is heading. James Michener was an avid sports participant while young and feels that it helped to strengthen his character. He was also in the Navy during World War II where he knew various leaders both with and without the experience playing various sports. He also traveled the world

Abstract: The object of this lab was to determine the relationship between the strength of a the magnetic field of a Helmholtz coil and the distance from the coil, along its central axis. Calculations for this relationship are in the predictions section below. The field was measured at eleven different points (5 on each side and one in the center) and recorded using a Hall Probe. Introduction: The example given in the Lab Manual1 was for studying bacteria. Helmholz coil was to be used as

A clone writes Sharing your DNA with someone does not make you the same person, says Lowri Turner By Lowri Turner, Friday January 10, 2003 The Guardian 5 I am a clone. Even writing that feels odd. I might as well say I am a tomato, or a VW Beetle, or a leather three-piece suite with free footstool from DFS for all the resonance the word "clone" has for me. I don't feel like a clone. I don't think I look like a clone. And yet, strictly speaking, I am one. I am an identical twin. I am an exact

Apparatus SF-8607 Basic Current Balance (Main Unit, 6 Current loop PC boards, Magnet Assembly with 6 magnets), DC power supply, DC ammeter, Balance, Lab Stand, hook-up wires with banana plug connectors Theory A current-carrying wire generates a magnetic field surrounding the wire. When this wire is placed in an external magnetic field, it experiences a force due to the poles of the two magnetic fields interacting
