Magnetic Abrasive Finishing Process

What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.

The current has a positive charge in one side of the coil and it transforms to negative when it gets to the other side of the coil. This charge controls the magnetic field, making the like charges repeal and the opposite charges attract.

instrument they used is described as an iron tube or vessel that was filled with a powder or

Various Machining and Metallurgical Processes such as Shaping, Turning, Milling, Grinding, Welding, Brazing, were used. The product was designed in a way to facilitate the large scale production of it.

Old iron smelting places used something called bloomeries. These odd furnaces looked like beehives with an opening in the side and top. They filled these bloomeries with charcoal and iron ore. They would then pump air into the bloomeries using bellows. They'd then take the blooms of iron and strike them on an anvil over and over.They would continue to do it until the impurities were gone. This finished product was called wrought Iron. (Blacksmithing History 1. (n.d.).)

A neodymium magnet and a powerful magnet also help balance the body's chakras (energy sources found

There are three requirements for the magnetic fields: “A large reservoir of fluid that can conduct electricity

We first propose using thick copper as the material we chose for wire type. We propose using thick copper because, in the trials, the electromagnet with string wire could only hold 0 filings, the electromagnet with aluminum material could hold 31 filings and the electromagnet with a copper wire could hold 83 pieces of filing. The pattern shows

through electromagnetic induction which create resistance, and in turn either heat or electricity. In this

In this graph, the magnetic field (B) is equal to 1/B. As displayed in the graph, 1/B is inversely proportional to the distance from the field sensor to the rod (R), which allows the graph to correspond to the expression of the magnitude of the magnetic field (B) in a current carrying wire when there is a change in distance. The current (I) remains constant in this part. Lastly, in part 2 of this lab, we analyzed the magnetic field of the magnet. Magnets can exert a force at a distance, just like electric charges. Magnetic fields permeate space and are strongest near a permanent magnet (magnetic dipole) or electromagnet (electric dipole); therefore, the power supply and ammeter were not required in this part. Part 2, consisted of determining the relationship between the magnetic field strength and the distance from the magnet. The graph 1/B vs. R^3, is the most linear out of the three. This graph corresponds the best to how we know a change in distance affects the magnetic field strength of a magnetic dipole, because the relatioship between a magnetic dipole and distance is inversely proportional. As the distance between the rod and the magnet increases, the magnetic field strength

are 3 key things to remember when it comes to magnetism and they are listed

These are usually the two places that magnetism is the most powerful. These poles are called the north seeking poles and south seeking poles. When you put two alike poles together, for example, two north seeking poles, they will fight and repel against each other. When you put a south and north seeking pole together with a south seeking pole, they are attracted to one another and stick together. The attracting, or repelling of magnets, depends on how close they are. They also depend on how strong their magnetic fields are. The further apart magnets are the less attracted they are to each other, The same goes for how much they are attracted to each other. Magnetic force strength depends on how big and how far apart magnets are. When a magnet is broken into little tiny pieces, a north pole will appear at one end of it along with a south pole. No matter how small or big the pieces are, they will still all end up having a north pole, and a south pole. The larger a magnet is, the stronger it becomes. Also the closer it is to an object the stronger it will become. This is how most normal magnets behave(“Website,”

The Smoothing Iron have been used for hundred of year. In the 1300’s, Greeks would have to use a metal paddle in which the person who had it would beat the clothes, hoping the pounding would remove the wrinkles (MagLab).. Many different irons were invented by the 200s. Henry W. Seeley, created the very first electronic iron on June 6, 1882, in New York City (MagLab). Henry W. Seeley’s first electronic iron was a cordless iron on a stand, that heated up by electricity. Seeley’s electric iron weighed up to fifteen pounds.

Magnetism can attract magnetic objects or push them away. Magnets have a magnetic north pole and a magnetic south pole. If the same pole of two magnets are placed near each other they

The V-belt from the motor drives a pulley in the front part of the head, which in turn drives the spindle. The spindle turns the drill. Two head assemblies are shown in Figure 9.2 b and c. Speeds on a stepped V pulley drive are changed by changing the position of the V-belt (Fig. 9.2b) Speeds on a variablespeed drive mechanism are changed by a hand wheel on the head. (Fig. 9.2c) The spindle must be revolving when this is done. Quill assembly: The spindle rotates within the Quill (Fig. 9.5) on bearings.
