illustrate‚ my high school was divided into two; the top floor was the magnet program and the rest of the school was for regulars. The schools physical structure depicts the social class within the school system that students are categorized into. Ironically‚ I was enrolled in the regular school‚ but because of my outstanding GPA from middle school my classes were a mixed of both magnet and regular. As a result‚ by being exposed to both magnet and regular classes I witness the inequalities within my schools

The Shepherd Magnes The most popular legend accounting for the discovery of magnets is that of an elderly Cretan shepherd named Magnes. Legend has it that Magnes was herding his sheep in an area of Northern Greece called Magnesia‚ about 4‚000 years ago. Suddenly both‚

to 15. The steps I would use would be to: 1. Using some magnetic manipulatives I would start with a group of 10 magnets in one group on a white board and 5 others in a different group on the board. I am using the magnets because they are easy to move around and the white board allows me to write and erase the name of the number down below the magnet. There is no pattern to the magnet placement in the large or small group. They are randomly placed inside the group. 2. I would start by

ANSWERS TO GUIDE QUESTIONS 1. What happens to the distribution of magnetic flux lines when the iron ring was placed in between the U-magnets? Magnetic Flux‚ by definition‚ is the measure of the quantity or the strength of the magnetic force in a given area‚ whether a closed or an open area. When the iron ring is placed in between the U-magnets‚ there has been a region by which has been enclosed‚ following the area of the iron ring. And according to Gauss’s Law for magnetism‚ the total magnetic

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

field :- The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. b) Magnetic field lines:- Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move. The magnetic field lines around a magnet can be observed by sprinkling iron filings around a magnet. It can also be observed by moving

Experiment 4 Measurement of e by Thomson’s bar magnet method. m Apparatus: Cathode ray tube (CRT) with power supply unit‚ one pair of bar magnets‚ high resistance voltmeter‚ magnetometer‚ stopwatch. Purpose of experiment: e To measure the specific charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT.
