Electric field

The science experiment that my partner and I are going to test is, do different brands of batteries affect the electric current of an electromagnet? Electromagnets are magnets that can be powered on and off, they can do simple tasks such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength.…

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…

processes 5225FiTransport properties I. INTRODUCTION There has been significant recent work on Vlasov-Maxwell (VM) equilibria that are consistent with nonlinear force-free1–8 and “nearly force-free”9 magnetic fields in Cartesian geometry. Therein, force-free refers to a magnetic field for which the associated current density is exactly parallel, which is the definition we shall also use ∇×B=μ0j, j×B=0.These works consider one-dimensional (1D) collisionless current sheets, with Refs.…

in a rotating magnetic field and thus a rotating force can be attained. The rotor is a rotating conductor and is mainly produced in cage shape. The stator generates the rotating magnetic field. The rotating of the magnetic field is not achieved by mechanical principle rather by applying AC current to the stator. The AC current applied to the electro-magnetic results in the rapid changing of the polarity of the magnetic field and make it equal to a rotating magnetic field. Brush conmmutator is…

Task 1 Part A Shell Oil Company globalization impacted the Ogoni culture in the Niger Delta, Nigeria (Unknown, UNPO, 2009). In 1956 Shell Oil Company, out of Britain found oil deposits and commenced drilling the Niger Delta (Unknown, UNPO, 2009). Before the oil industry globalization, the Ogoni culture had a culture of tradition expanding over 500 years. Furthermore, the Ogoni culture lived off the land, without repercussions from today’s modernization, laws and technology. The Ogoni culture…

Do you remember that shooting that happened in the United States? The one where a man was killing in a public center? He had access to automatic weapons? It 's probably hard to know which one since it happens almost every day. It has become common news to hear that someone has been shot and killed. So many people die to the bullet, people have taken to buying more guns to fight against this terrorism. However, the solution to gun violence isn’t more guns, unless they are in the hands of someone…

average. This increase is due to the fact there is an increase in demand for faster, less expensive, and more efficient technologies” (“Labor Market”). Although being a mechanical engineer doesn’t pay the highest people tend to acquire jobs in this field in order to keep advancement in technologies flowing. “Electrical advances keeps employment high and the development of new devices is necessary for advancement” (Texas Workforce Commission). The development of new technologies opens many job…

possible until the last 60 years until the 1950s countries like Italy or Germany had laws in place which prohibited for female teachers to be married. Overall the 1800 and 1900 hundreds really made a difference in the development of women rights in the field of science especially through the inventions of the industrial revolution new and cheaper possibilities for educations could be used. Furthermore, political developments like the school attendance law of Napoleon or…

little. The “perfect” society was those that work as laborers. People were executed if thought of sabotage. The prisoners’ ability to work determined their survival. If the prisoners couldn’t perform daily labor, they were killed. Professionals in any field were murdered, they abolished political and civil rights. Families were separated into different labor camps. Hospitals and places of learning were all shut…

compass experiment and receiving successful results, we moved on to our last experiment of the unit. This experiment was called “Through it All.” During this experiment, students worked in small groups to test the strength of the magnetic force field through a variety of objects. Before breaking off into groups and performing the tests of each item, students were required to make a prediction about whether or not they thought a magnet could attract an object through each item to be tested.…
