The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets‚ it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type‚ middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. The common things have magnetite iron ore (belong to strong

magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were then constructed based on the specifications that had been identified after the preliminary testing. The prototype car’s magnets were permanent magnets while the road magnets were electromagnets. They had been oriented so that the magnets would repel each other. | Investigatory

Electromagnet Simulation http://www.fossweb.com/modules3-6/MagnetismandElectricity/activities/electromagnet.html This is an interactive simulation of an electromagnet. Your goal is to test the different factors that can change the strength of the magnet (i.e. how many fillings it can pick up). For

Project #15: Make Homemade Glue from Milk With milk‚ white vinegar and baking soda‚ you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster‚ or work on different materials (wood vs. plastic vs. paper).

different aspects of one force. This force is called the electromagnetic force. Electricity can be generated by rotating coils of wire in the vicinity of a magnet. When a force moves objects toward and away from each other it is called electricity. When it comes to magnets‚ Earth and other planets behave like giant magnets. The first know magnets were iron materials. If one piece of the iron was placed in contact with the other‚ it attracted it. In ancient times men knew of a special kind of rock that

How do the writers present and use symbolism in the extracts from “The Go-Between” and “Spies”? The extract from Michael Frayn’s ‘spies’ hints at imprisonment‚ as though the character is trapped in his past. Frayn portrays this to the audience through the symbolism of a jug. Not only does the jug represent a memory for the character‚ but the lace‚ which is ‘weighted down with four blue beads’‚ is used as a metaphor for showing that the events of his past are‚ like the beads on the jug‚ weighing

Latin Immigration February 12‚ 2012 The Bracero Program The Bracero Program was a system put in place from 1942 to 1964 to recruit Mexican farm laborers during World War II to supplement a temporary work force in the United States. In hopes of making enough money to buy land and create more lucrative futures‚ many Mexican workers left their families to work in the Bracero Program; unfortunately the U.S. was the only country that truly benefited from the work of the Braceros and continues

Kevin Williams Project 1 The use of electricity and magnetism in transportation When Benjamin Franklin discovered electricity‚ it was probably one of the biggest discoveries known to mankind. Even though our dependence of electricity is a lot‚ however at the same time it’s easy to forget how dependent we actually are on it. Electricity always has and always will play a huge part in our everyday life. It’s hard to imagine humanity without it. When it comes to transportation‚ it is going to rewrite

Analysis of experimental data showed that change in surface roughness (ΔRa) was highly influenced by mesh number followed by percentage weight of abrasives‚ rpm of permanent magnet‚ and finishing time. Key Words: Magnetic abrasive finishing (MAF)‚ Design of experiments‚ Surface roughness. 1. Introduction Fine surface finish is in high demand in a wide spectrum of industrial applications.
