Finding the Charge to Mass Ratio of the Electron Via a Uniform Magnetic Field Generated by Helmholtz Coils Abstract The charge to mass ratio of the electron was found to be [pic] with a percent difference from the accepted value ([pic]) of 1.1% when adjusted for the Earth’s magnetic field. Without taking the Earth’s magnetic field into consideration‚ the charge to mass ratio was found to be [pic] with a percent difference of 5.3%.

Schlosser also addresses the high number of migrant workers working today‚ as well as being the poorest workers in the United States. Yet‚ Schlosser does not touch on the health risks that represent working in the fields. I plan to emphasize more on the health risks that are present in the everyday life of a migrant farm working. I will discuss how pesticides have a negative effect on the life of workers‚ but also to their families. Children of farm workers are at

Electromagnetism and Modern Technologies The invention of electricity has benefited mankind in several aspects of life ever since the 1800s. Over the course of the past two centuries‚ scientists have been developing theories that serve as the backbone for various devices today. Such intellectuals have been attempting to understand the credibility and applicability of the already existent theories‚ such as electricity and magnetism. In addition‚ they have introduced new concepts by either creating

Ultrasounds are becoming a common diagnostic procedure in the medical field because they can measure and detect abnormalities. Ultrasound instruments which are also known as sonographic instruments operate by using high frequency sound waves. These sound waves operate using a frequency range of 1 to 18 megahertz that can be used for imaging. These high-frequency sound waves are out of range of human hearing. The lower frequency of the sound waves produce less resolution but can produce images

John McCrae: A Canadian Poet “In Flanders fields the poppies blow Between the crosses‚ row on row‚ That mark our place‚ and in the sky‚ The larks‚ still bravely singing‚ fly Scarce heard among the guns below.”(McCrae‚ 1). John McCrae was born in Guelph‚ Ontario Canada. He was the second son of Scottish immigrants‚ David McCrae and Janet Simpson Eckford McCrae. His father was a woollen manufacturer. He began to write in Guelph College Institute. John was always a remarkable natural attraction

most important uses for electromagnetism is in electronic motors. The main components are a core rod and many copper wires coiling around the iron rod. The coils rotate around the iron rod because of the magnetic force caused by a certain magnetic field on an electric current. While doing so‚ this turns electrical energy into mechanical energy. When this happens‚ normally a gear is attached to the end of the rod. That Gear is connected to another gear and that can be linked to anything you want to

that highlights this difference. Imagine that both the ideal conductor and superconductor are above their critical temperature‚ Tc. That is‚ they both are in a normal conducting state and have electrical resistance. A magnetic field‚ Ba‚ is then applied. This results in the field penetrating both materials. Both samples are then cooled so that the ideal conductor now has zero resistance. It is found that the superconductor

actually saying that it is able to be acted upon by a magnetic field. When electricity flows through a circuit‚ it creates a magnetic field.When a magnet cuts across a circuit‚ a voltage is produced. 2. Discuss the relationship between electric and magnetic fields. (HINT: Be sure to discuss what happens when electric current is applied to a magnetic field.) The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating
