Since MRI uses an extremely powerful magnetic field capable of moving metal objects, the person can not make an MRI if a metallic implant, such as a pacemaker, an implantable infusion pump, or if an artificial joint, plates and screws implanted metal or metal surgical staples. It may also be necessary

Introduction 2) Synchronous machine structures 3) Rotating magnetic field 4) Equivalent circuit model 5) Performance as a generator 6) Performance as a motor Introduction A synchronous machine is an ac rotating machine whose speed under steady state condition is proportional to the frequency of the current in its armature. The magnetic field created by the armature currents rotates at the same speed as that created by the field current on the rotor, which is rotating at the synchronous speed, and

this is: where J is the current density at a given location in a resistive material, E is the electric field at that location, and σ is a material dependent parameter called the conductivity. This reformulation of Ohm's law is due to Gustav Kirchhoff Ohm's law is an empirical law, a generalization from many experiments that have shown that current is approximately proportional to electric field for most materials. It is less fundamental than Maxwell's equations and is not always obeyed.

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

Mrs. Fields’ Cookies Case Study Assignment 1. Would you describe Mrs. Fields’ Cookies as more of a functional hierarchy structured along traditional functional lines or more of an IT-enabled network consisting of tailored business processes? I would describe the organizational structure of Mrs. Fields’ Cookies as being an IT-enabled network consisting of tailored business processes. Throughout the different sections of the case study, several examples support the notion that Mrs. Fields’ organizational
