Field Experience Summary I chose to do my field experience in Garland ISD at Freeman Elementary school. It’s located off of Walnut near Garland rd in Garland‚ Texas. I wasn’t sure what to expect‚ since this is my first time observing in a classroom. The Asst. Principle placed me in two different classes. They were both a bilingual‚ but one was second grade and the other one was fourth grade. I decided to learn how teachers communicate with the parents of the students that are in their

The computational domain is simply the physical region over which the simulation will be performed. The E and H fields are determined at every point in space within that computational domain. The material of each cell within the computational domain must be specified. Typically‚ the material is either free-space (air)‚ metal‚ or dielectric. Any material can be used

characteristics. Electromagnetism has always been the driving force behind electric motor technology. But these motors suffer from many drawbacks. The field of ultrasonic seems to be changing that driving force. DRAWBACKS OF ELECTROMAGNETIC MOTORS Electromagnetic motors rely on the attraction and repulsion of magnetic fields for their operation. Without good noise suppression circuitry‚ their noisy electrical operation will affect the electronic components inside it. Surges

It is a type of scan that is used in medical settings to evaluate and come to a diagnostic conclusion of the body. This process involves the use of both strong magnetic fields and radio waves in order to produce the image needed to assess the person’s well being. The MRI scan has proven to be effective in examining different parts of the body‚ and the following are examples: Brain‚ spinal cord‚ internal organs‚ heart and blood vessels‚ bones. A normal human adult will have up to 60% of water within

Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles

What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.

Semiconductors: Band Gap of Germanium and the Hall Effect Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar February 14‚ 2014 PreLab With the new understanding of quantum mechanics and solid-state physics in the 1930’s came the development of semiconductors. Semiconductors are materials such as silicon and germanium in which the current density is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant
