Electromagnetism

This paper examines the magnetic field separated by a superconductor material. Magneto static or dipole-dipole forces are very critical in determining the microstructure of any magnet. Magnetic fields in magneto statics which are constant at a particular moment in time always produces steady currents. The charge passing in a wire at per unit time is called the current of that particular wire. Conventionally, it is assumed that electric current always flow in the direction of the movement of the positive charges.
Nonmagnetic materials which are conductors can shield the magnetic field to some extent. Some non-magnetic materials which are conductors help shield magnetic field. A good example is a superconductor, when this material is placed between two magnetic materials; it tends to exclude the magnetic fields created by the magnets. A superconductor material behaves like a magnet in that if the South Pole of the magnet is brought near it, the magnet behaves as though it is being approached by itself from the other side the superconductor.
Magnetic fields come about due to electric currents. If these magnetic fields are changed by moving the magnet near a non-magnetic material or metal, it induces electric field that is the difference in voltage in the metal. This then produces a magnetic field which is oriented in the direction opposite to that of the magnet.
For a homopolar motor, the battery produces electric current which then moves in a radial manner through the magnetic disc. ...

Electrical Engineering in Telecommunications
The next step is for telecommunication engineers to outline a transmission and reception of the transmitted information. In designing the transmitters and receivers, the engineers have to factor in the power consumption especially of the transmitters since a weak signal will due to low or insufficient power will be susceptible to corruption by noise so that the sent information is received as jumbled or incoherent. Looked at simplistically, two telephone handsets connected together need a battery in between to provide the electrical signal to transmit voice signals as depicted below; d1 d2…

Electrical Cars Research Paper
It is estimated that more than one third of the total energy such as natural gas, diesel, and gasoline in the world goes to driving automobiles. Today, auto industries are in the toe-tip of enhancing transition into electrical cars. This is because of several forces that limit growth of the oil industry and automotive businesses. These limiting factors have made engineers implement varieties of propulsive systems that require other forms of energy instead of oil. General Motors has, therefore, come up with very promising configuration of battery electric vehicles (BEV) to supplement combustion…

This was not difficult as I was in love with and excelled in mathematics and physics; I was not very strong in the arts so I opted to major mostly in technical fields. After I graduated from high school, I secured a place in college where I was advised that if I hope to become an electrical engineer, I should minor in chemistry or a management subject. I am hoping to graduate in with a GPA high enough to get me into any of the many great universities in the United States; preferably, I would like to go to MIT or Stanford. As such, I am working diligently as I cannot afford a dismal GPA since…
