North Magnetic Pole

The North and South have always followed different paths and by the mid 1800’s the differences were even more pronounced. The North was becoming more industrial, dedicated to immigration, free labor and supported a federal government. Slavery was not common in the North and it was even banned in some states. The South’s agricultural economy was founded on slavery and cotton and they supported a government that allowed states to make their own rules. Southerners viewed the North and their views…

example, in the American Yawp, said that “northern workers felt that slavery suppressed wages and stole land that could have bend used by poor white Americans to achieve economic independence” (TAY). This quote means that slave has migrate to the north and it is unbalance over the lower class people. In addition, lower white people has a lot of competition in jobs due to that slavery are trying to find a jobs as well. This maybe lead the economy to produce money slowly because most slavery do…

Unlike the North, Southern states did not industrialize and remained primarily rural. The North and the South started to become very different when Elie Wiesel invented the cotton gin. The cotton gin could work as fast as 50 people working by hand. Since cotton could be processed more easily, Southern planters wanted to grow more cotton on fields. White landowners that started a business selling cotton depended on slave labor to plant and pick cotton. Later on, the South only accounted for only…

Magnetic Resonance Imaging (MRI) is a medical technology that uses magnetic fields to interact with protons in the human body, producing an image that allows doctors to diagnose disease and/or injuries (DiGiuseppe, Haberer, Salciccioli, Sanader, & Vavitsas, 2012). The idea of MRI technology had come from Raymond Damadian who was a medical professor and had founded the company that manufactured MRI scanners (Bergman PH. D, 2015). In the beginning, Damadian had been using Nuclear Magnetic…

maintains the magnetic flux and produces a particular value of the flux density B at that point in a magnetic field. Therefore the flux density is the cause while the flux density (B) is the effect. The flux density can be assumed proportionally to the field intensity in a magnetic field which comes in three parts. First part is: Where U stands for the permeability of force (the measure of the degree to which the magnetic line of force can penetrate the material). The value of magnetic space…

Maxwell and Faraday- A Brief History of Electromagnetism The field of electromagnetism was established in 1819, twelve years before Maxwell was born. Hans Christian Oersted from Denmark was the first scientist who thought of the possibility that magnetism and electricity were related. He considered such a possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when…

the two circuits. The value of the coupling capacitance decreases with increasing separation of the circuits. Inductive coupling on the other hand is caused by mutual inductance between two conductors. When current flows through wires it produces a magnetic flux, which can induce a current in adjacent circuits. The geometry of the conductors as well as the separation between them determines the value of the mutual inductance, and hence the degree of the inductive coupling. Typically, capacitive…

provide movement for a vehicle. When an electric current, magnetic field or external force acts on a coil found inside of the motor, it will provide force to it, thus causing the coil to move, the coil rotates on a half turn basis otherwise the motor is forced to stop and will not move. The Motor Effect Motor effect refers to a current carrying wire in place of a magnetic field, the wire experiences a force, instead of the magnetic field producing it. You can measure the force by using the…

samples were also calculated which is known as squareness ratio. The materials having high value of coercivity show the hard magnetic materials and this behavior was observed in M-type hexa ferrites [36]. The measured values of coercivity ‘Hc’ for all the samples were observed in the range of (1.38-2.06) KOe. All the samples have high value of coercivity showing the hard magnetic behavior of M-type hexa…

Monday, the start of yet another school day. Another day where he 's absent. Another day not learning anything. Another day where he won 't see and talk to his friends again. The opened window brought in cool air, swirling around the average hospital room. Unfortunately, this made the eleven-year-old boy shiver nonstop and his teeth clattering like a skeleton would. His front bangs of his silver-dyed hair brushed upwards, for the air sometimes liked to mess around with it, showing the child 's…
