Magnetic fields

has its own disadvantages and there were no other options available till the beginning of the 20th century , but with the development in technology there were other means of transport which came into action and one of which was the MAGLEV TRAIN (Magnetic levitation train) which are on entirely different level as when compared to our traditional trains and on the other hand can been compared to aero planes in terms of speed. The recent development of maglev train has made them a strong contender

Abstract Magnetic polymer nanocomposites have attracted broad interest for hyperthermic cancer treatment because they are non-toxic, biocompatible, and can be remotely heated by alternating magnetic fields. The magnetic induction heating behavior provides a great benefit in biomedical applications, such as targeted drug delivery, and magnetic separation. In situ formation of an organic or polymer layer on their surface is one of the efficient methods for decreasing the aggregation between the nanoparticles

effects for its magnetic field, eddy current distribution, forces according to the secondary relative permeability, and conductivity. The results given here are purely analytic & applicable. I. INTRODUCTION Magnetic brakes Magnetic brakes are a relatively new technology that is beginning to gain popularity due to their high degree of safety. Rather than slowing a train via friction (such as fin or skid brakes), which can often be affected by various elements such as rain, magnetic brakes rely completely

BACKGROUND INFORMATION Airport security is currently seen as one of the biggest inconveniences attributed to travel. However a brief look back in history to some of the conditions frequent flyers were subjected to makes modern air travel look like a breeze. Some of the earliest attempts at flying required an excess of manpower. Leonardo da Vinci is credited to be the first to design basic flying machines called ornithopters, that gave man mechanical wings. Through a system of pulleys the wings could

comprise a stationary field commonly referred to as stator, and a rotating field (or rotor). According to Krishnan, (2010), the mechanism of operation of DC motors is based on the interaction between electric current and the

it will probably be easily understood, but none the less intriguing. Magnets have intrigued people for a long time; they were discovered long ago. Certain rocks and ores of iron called lodestones were found. These lodestones which were naturally magnetic rocks made of the mineral magnetite, were so mysterious to

the wire to spin. You can change the way the wire spins but flipping the magnet over. The motor uses the attracting and repelling forces to make the wire spin. If you use stronger magnets the force will be greater. If you coil the wire more the magnetic field will get larger. But you cannot put to many coils in it or it will become too heavy. If you have wire with a coating you will have to scrap it off for it to work. If you put the support braces to far apart that can also become a problem. You

Introduction Induction machines are classified into two which includes motors and generators. The basic principles of these motors can be applied and hence develop equations describing its behaviour. The most common motors include squirrel-cage, wound-rotor ranging from few horsepower to thousands as the case may be. Squirrel Cage Rotor consist of a bare copper, slightly longer than the rotor, while a wound rotor has a 3 phase windings, and are evenly distributed in the slots, usually connected

1.758820024(11)× 〖10〗^11 C/kg). To recreate the experiment, we will use the electron gun to generate an electron beam and induce a magnetic force, equivalent to the magnetic part of the Lorentz Force 〖( F〗_(e,mag)=-e ( v × B ) ), that will curve the beam counterclockwise into a circle (set-up shown in Experimental Description and Results). We can equate the magnetic force to the centripetal force required for uniform circular motion (Equation 2) and use the law of conservation of energy to relate

Magnetic biasing and stabilizing techniques are commonly used to enhance the linearity, sensitivity, and dynamic range of magnetic sensors, and to suppress the Barkhausen noise induced by domain wall motion.
