the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found evidence that magnetic field lines go from a north magnetic pole to a south magnetic pole. These results were seen in all three magnetic devices. When determining the magnitude of the electric field in the Helmholtz

INTRODUCTION If an electric current flows through a conductor in a magnetic field‚ the magnetic field exerts a transverse force on the moving charge carrier which tends to push them to one side of the conductor. A buildup of charge at the sides of the conductors will balance this magnetic influence‚ producing a measurable voltage between the two sides of the conductor. This presence of measurable transverse voltage is the Hall Effect. The Hall effect was discovered in 1879 by Edwin Herbert Hall

for a magnetic motor vitality. The standard ways that the energy produced from magnet is significantly far more cost effective and eco helpful. A magnetic device incorporating the use of permanent magnet turning with a rotor to generate a magnet energy which is then circuited to other mechanism to do so useful work. Magnetic principle can utilize in units of various sizes. Magnetic units can be microscopic or mile wide‚ as long as the correct principle are maintained. When magnetic fields are properly

when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic Force: the attraction or repulsion between magnetic poles Magnetic Fields: Magnetic Field: the area of magnetic force around a magnet Magnetic Field Lines: invisible lines that map out the magnetic field around a magnet. Magnetic field lines spread out from one pole

Electric Fields Lab Abstract: In this lab we will study the equipotential lines in an electric field in order to study the structure of the electric lines of force. We will plot the position of electric field lines in a given electric field using both a manual method and a computer software program. There is an electric field in any region where there is a force on an electric charge at rest. It is convenient to represent an electric field by the

Define/describe each of the two Mag-lev vehicle systems‚ identifying similarities and differences. Answer: Electromagnetic system is a system that allows each vehicle to warp around a T-shape guide way. Electrodynamics systems are systems that utilize magnetic repulsion rather than attraction. The similarities between these two Mag-lev vehicle systems are that they both utilize magnets. However the difference between them is that one looses all their resistance and other still has it. Although the similarities

looking out for highly energetic gamma rays‚ as some has been found recently. The astronomers do know‚ however‚ that these gamma rays did not come from the same origin as the cosmic waves‚ as the gamma rays did not deflect off of the Milky Way’s magnetic field. Though they haven’t found the origin of these rays yet‚ astronomers are on the right path to get there. If it takes months‚ or years‚ they won’t rest until answers are given‚ thus expanding our small intergalactic knowledge. This article was

Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron‚ which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons‚ orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin‚ which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum
