This deflection convinced him that magnetic fields radiate from all sides of wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism. He published his findings, proving that an electric current produces a magnetic field as it flows through a wire. The CGS unit of magnetic induction is named in honor of his contributions to the field of electromagnetism. The magnetic field encircles this straight piece of current- carrying

The field of Human Services is limitless; While Human Service itself has such a broad definition, the work of the field speaks in volumes as the needed of the people are addressed. The Human Service field has a wide variety of occupations and areas within its umbrella, all sharing one basic objective of providing a service to someone in need The main objective of the field is to provide services to people struggling to survive vulnerable times in their lives and need additional supports to become

CHAPTER 1 INTRODUCTION 1.1 General The micro-emulsion inks have a wide range of applications in industry. The ink used earlier for printing purposes contributes to pollution in environment. The pollution is by means of emission of volatile organic compounds (VOCs) which are present in the form of an aliphatic solvent. Emission of VOCs from these solvents and their discharge in waste streams are quantifiable. For example a typical medium size cold – set web plant uses 40,000 kg per year

and repeat the steps above after you’ve let the compass stabilize. 11. Click on the electromagnet tab. Place the compass on the left side of the coil so that the compass center lies along the axis of the coil. (The y-component of the magnetic field is zero along the axis of the coil.) 12. Move the compass along a semicircular path above the coil until you’ve put it on the opposite side of the coil. Describe what happens to the compass needle. 13. Move the compass along a semicircular

Abstract The purpose of the overall experiment is to given a certain distribution of charge and map the electric field by identifying the equipotential surfaces/lines around the charges. Four templates are investigated, such as parallel strips of metallic paint, concentric rings. In the lab, we confirm that the electric field line is orthogonal to the equipotential line. We can also demonstrate that as one gets closer to an electrode, the equipotential contours approach the shape of the electrodes

bar changes the device into somewhat of a magnetic sensor. In essence, the pickup “feels” the vibrations of the strings disrupting its magnetic field, and translates that into an electrical charge [ (Henshall, 2011) ]. “The basic science behind pickup function is Faraday's Law of Induction. It states that a changing magnetic field causes an electric field to be set up in a nearby wire, causing a current to flow if the wire is part of a closed circuit (a loop of wire for example)” [ (Wallace, 2004)

per unit area perpendicular to the magnetic field. Weber: SI unit of magnetic flux. (Wb) Tesla: SI unit of flux density, equal to one weber per square meter. Gauss: unit from the CGS (centimeter-gram-second) system, unit of flux density. Hall Effect: The change in current density produces a small trans- verse voltage in the material. Electromagnet: Produces a magnetic field only when there is current through a conductor

‘’Insignificant Gestures’’ by Jo Cannon In 2007 Jo Cannon published her essay ‘’Insignificant Gestures’’, which portrays a young doctor’s time as a district health officer at the age of twenty-eight in Africa. When the doctor returns from Africa, he was fed up with the disgusting odor of blood and starvation. Therefore he retrained as a psychiatrist. During the time he spent in Africa he had a young servant named Celia, who lived with him in his house, and her main tasks were to iron his clothes
