  • Maxwell And Faraday Research Paper

    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 current was passing through the wire. André Ampère was greatly inspired by Oersted’s findings and worked on it to create a mathematical formula that later became Maxwell’s fourth equation of electromagnetism in the year 1821. (Peters, 2000) Around the…

  • The Four Fundamental Forces

    that electric currents make magnetic fields. This impacted the concept of electromagnetism heavily. Before Oersted, people knew about magnetic and electrical force, but no one had thought of the combination of the two. Oersted is known for discovering electromagnetism and aluminum. Expanding on Oersted’s discovery, André-Marie Ampere discovered a wire carrying electrical current can attract or push away an additional wire. In his honor, there is an SI unit symbol of electrical current called…

  • Michael Faraday And Oersted Compare And Contrast

    Hans Christian Oersted. They came from different family backgrounds, Faraday being from a poor family and Oersted’s father was a pharmacist. Oersted attended the University of Copenhagen at the age of 16 and eventually earned his PHD in Philosophy. Faraday, because of his families poverty and only received a basic education but was able to educated himself by reading books and attending lectures. Faraday based his discoveries from Oersted’s publications where as Oerstad used experiments.…

  • Oersted's Theory Of Magnetism Essay

    Davy’s Journey Towards Electromagnetism During the early 1800s, scientists made observations that were tested repeatedly and then were seen as fact. Until 1820, electricity and magnetism were believed to be separate branches on the tree of science. Once others believed that idea it became cemented in to the scientific community. However, Humphry Davy was a chemist whose determination and experimentation overturned that idea. Despite obstacles, Oersted’s and Davy‘s experiments changed his peers’…

  • Magnetic Propulsion Essay

    Magnetic propulsion Magnetic propulsion refers the use magnetic energy to move objects from one point to another. Due to increased demand for clean energy, the use of electromagnetic propulsion will also be a new way of powering the future vehicles. This method employs the use of electrical current to create an opposing magnetic field that results in repulsion. The electromagnetic propulsion has been in use in motors to create a rotational force which drives the vehicles wheel forward.…

  • The Reflection Of Mechanical Power

    Mechanical power is defined as torque and RPM (rotation per minute) and electric power is defined as current and voltage. Therefore, in order convert mechanical power into electric power, torque shall be converted into current and rpm shall be changed into voltage. The relation between the rpm and voltage can be defined with equations with the use of Equations. When there is a decrease in value in equations there is an increase in efficiency of power generator. In here, there is no loss when …

  • Physics: Quantum Classical Expretation Of IQHE)

    Table of content Introduction Two dimensional electron system Hall geometry Classical interpretation of IQHE Quantum mechanical interpretation of IQHE Significance of IQHE References Introduction The integral quantum hall effect (IQHE) was first discovered by Klaus von Klitzing and coworkers in 1980. It was demonstrated by two dimensional electron system in a device called metal oxide semiconductor field effect transistor (MOSFET), under low temperature and large magnetic…

  • AC Voltage Advantages And Disadvantages

    AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the…
