For each of them describe their properties in terms of: conductivity, resistivity, tensile strength and rigidity. Then give an example an electrical use for of each of them. http://m.kkhsou.in/EBIDYA/BPP/MODIFY_electronics.html Conductor:- Which the material

whole body MRI structure includes a couple sets of symmetric coils that normally makes an exceedingly homogeneous field quality in the extent of 1.5 T to 3.0 T, and the apex peak homogeneity should be better than 10 ppm over a 40 ∼ 50 cm DSV. Numerical change techniques accept a basic part in homogeneous magnet design technique with adequately ensured framework, which commands the field quality over DSV region, construction costs and market forcefulness of the thing. Techniques using different numerical

the first wire. 43) The metal wing of an airplane acts like a “wire” flying through Earth’s magnetic field. A voltage is induced between the wing tips, and a current flows along the wing, but only for a short time. Why does the current stop even though the airplane continues flying through Earth’s magnetic field? -The current stops even though the airplane continues to fly through the Earth’s magnetic field, because the losses which occurred when a motor operates a generator and when the voltage

ric Field Definition of electric field (E) at a point in space: the electric force (F) acting on a positive test charge placed at that point divided by the magnitude of the test charge q0 E = F ----- q0 E = F ----- q0 * Where k is a constant called coulomb constant * The unit of charge in SI units is the (C) * k = (approximately) 9.0 x 109 N.m2/C2 Electric Field * Electric field lines are a convenient way to

different applications as a switch. It allows the signal to pass through the relay, when the magnetic coil is turned on, connecting 2 contact points together. It works as follows: The relay is made with a bobbin, a coil, a fixed magnetic core, and a movable armature. When the coil is excited, with the magnetic field generated, the armature is maneuvered such that it will be repositioned when the magnetic field is turned on so that the contacts touch and the signal travels through the relay. This design

that turns mechanical energy into electrical energy (Olivier 2015). A generator is usually either AC( alternating-current) or DC( direct current). An AC basic principle is that the coil rotates mechanically in a uniform magnetic field; this magnetic field then induces an electrical field. Due to a part of the coil always being connected to the same slip ring and brush it can be said that the brush is sometimes negative and sometimes positive (Olivier 2015). Although it’s easier and cheaper to

Superconductivity INTRODUCTION We've all heard about superconductivity. But, do we all know what it is? How it works and what are its uses? To start talking about superconductivity, we must try to understand the how "normal" conductivity works. This will make it much easier to understand how the "super" part functions. In the following paragraphs, I will explain how superconductivity works, some of the current problems and some examples of its uses. CONDUCTIVITY Conductivity

Much like electric fields, the magnetic field of an object can attract or push away another magnetic object. When an object is placed within a magnetic field the effect will happen along the field lines. Magnetic field lines are the strongest at an object 's magnetic poles and it 's at these poles where the field lines begin and end. The earth itself is like a large magnet, having a core made up of molten iron causes the earth to have a large magnetic field. The two poles of the earth (north

into electromagnets, Hans Oersted discovered that a conductor carrying an electric current was surrounded by a magnetic field (Bellis 2). Hans Oersted discovered this because his compass reacted to a battery when he connected them using wires.
