  • Wire In A Magnetic Field
    2,554 words
    Planning Aim and hypotheses According to Fleming's Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection be...
  • Young Near The Mid Ocean Ridge
    1,853 words
    Continental Drift, the theory that continents move slowly about the earth's surface, changing their positions relative to one another and to the poles of the earth. In the past the theory has been discussed but not generally accepted, most geologists believing the continents to be fixed in place and subject only to vertical movements, such as those observed during mountain uplift. In recent years, however, a sound body of evidence in support of a modified form of the drift theory has been found....
  • Magnetic Resonance On Bulk Materials
    556 words
    The measurement of nuclear and electron magnetic resonance on bulk materials was made possible by Felix Bloch and Edward Purcell and in 1952 they shared the Nobel Prize in Physics for their work. Until then, magnetic resonance was a measurable phenomena in which atoms were shot through a magnet as a beam. This was the work of Rabi. Therefore, the Nobel Prize quality in Bloch and Purcell's work was not in the theory of magnetic resonance itself, but in the development of instruments which would m...

    Why Maglev... MagLev technology is entirely different from any form of transportation in operation today, but the basic principles that lie at the foundation are not beyond the understanding of the beginning electricity and magnetism student. It is in the application of these principles to design and optimize an actual train that things get hairy. The basic idea has been researched since the mid-sixties, but it is only now that economically feasible prototypes are being built and governments are...

    Magnetic SusceptabilityMichael J. Horan II Abstract: The change in weight induced by a magnetic field for three solutions of complexes was recorded. The change in weight of a calibrating solution of 29.97% (W / W) of Ni Cl 2 was recorded to calculate the apparatus constant as 5.7538. cv and cm for each solution was determined in order to calculate the number of unpaired electrons for each paramagnetic complex. Fe (NH 4) 2 (SO 4) 2 EUR 6 (H 20) had 4 unpaired electrons, KM nO 4 had zero unpaired ...
  • Atomic Behavior Of Magnetic Materials
    520 words
    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 mom...
  • Magnetic Field B
    1,682 words
    Diamagnetics was discovered by Michael Faraday in 1846, but no one at the time thought that it could lead to any appreciable effects. William Thomson (Lord Kelvin), referring to levitation as the problem of "Moham ets coffin", had this to say: "It will ob ably be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble". Fields strong enough to lift d...
  • Magnetic Field Around A Single Wire
    1,305 words
    Research, p. 1 Do you want to know a secret? First, consider this: When a magician performs a magic trick, many ask, "How did he do that?" Well... the true magician never tells because it is a secret. But when speaking about magnetism and its use in our everyday lives, you can learn the SECRET-the secret of magnetism! A true scientist would be glad to share his secrets through experimentation. Thus, I will share the secret with you. It begins with science-physics, to be exact: matter and energy,...

    Hans Christian Oersted was born in Rudkobing on August 14, 1777 to Soren Christian Oersted and Karen Herman sen. His father was an apothecary and did not have the time to properly raise Oersted or his brother so they were raised by a German wigmakers. When he turned eleven, he went to work for his father at his pharmacy, where his first interest in science began. Without any prior schooling, except what he learned informally through others, he passed the entrance exam to University of Copenhagen...
  • Magnetic Flux Changes
    706 words
    Lenz's Law and Faraday's Law of Induction 1. With this definition of the flux being, we can now return to Faraday's investigations. He found that the magnitude of the emf produced depends on the rate at which the magnetic flux changes. Faraday found that if the flux through loops of wire changes by an amount, during a time delta t, the average induced emf during this time is This fundamental result is known as Faraday's law of induction. The minus sign is placed there to remind us in which direc...

    What factors affect the strength of an electromagnet? Introduction I will be testing the factors which will make an electromagnet stronger. Electromagnets are magnets which are created and are easily controlled by electricity. All magnets have a region of space around them called the magnetic field which exerts a force on any magnetic material such as iron and steel or any other magnet which enters it. This force can be attractive and repulsive. If an electric current flows through a coil of wir...
  • Form Of Magnetic Field Energy
    1,816 words
    My project's goal was to make a metal detector that can successfully detect pieces of metal (actually anything conductive) within a range of 15 cm depending on the object's conductivity and its surface area parallel to the plane of the search coil (and I did it! ). My detector is a simple one with almost no discrimination, which means that it will detects metal objects independent of their chemical composition or provides no further information about their properties. There are some specialized ...
  • Factors Affecting Strength Of Magnetic Field Of An Electromagnet
    1,442 words
    . Investigating the factors affecting the strength of an electromagnet. Background Knowledge: The theory of magnetism is the only way to explain the process of magnetizing an object. In an unmagnetised piece of iron the domains are pointing in numerous directions, which results in them cancelling each other out. However, a magnetized piece of iron would have all the magnetic domains pointing in all the same direction. This is due to the north poles being at one end and the south poles at the oth...
  • Number Of Coils Within The Magnetic Field
    304 words
    The parts of a motor are a team working together to convert electrical energy into mechanical energy. The parts, their descriptions and how they work are explained below: Armature The coil is wound onto a frame called an armature. It is usually made of ferromagnetic material (something that conducts magnetism well). The armature is usually free to rotate an axle called the armature axle. This sticks out of the motor and rotates with the coil and is used to do the work the motor is designed for. ...
