habitats. Once cells have reached their preferred microhabitat they would presumably stop swimming and adhere to sediment particles until conditions changed.” (Bazylinski). Magnetotaxis refers to the behavior of bacteria as they move along magnetic field lines. MTB are microorganisms that belong to a heterogeneous group of gram-negative bacteria and are a diverse group of aquatic

Christopher Brown Class 011-14H 23 Oct. 2014 The Split On 17 November 1775, Colonel Henry Knox was recognized as the “Colonel of the Regiment of Artillery” by Continental congress. On this day, Artillery as a whole was born. Even though Field Artillery and Air Defense Artillery are two separate branches now, both inherit Artillery traditions.The roots of the Artillery branch insignia goes as far back as 1834 in which the insignia that we have now was just two gold cannons were crossed over

demonstrate how maglev trains work with electromagnets. We will provide information about the history of early electromagnets. We will also provide information on the locomotion process, which is done through the generation of an electromagnet field by the rotor around the stationary magnet causing the torque from the magnet to pull or push it [1]. The paper will describe how each part of the electromagnet works. There are projects that we will discuss that helped further the development

There are two types of magnetic forces; push and pull. A magnetic field is the region around a magnet where the magnetic force works. The ends of a magnet are called poles. Like poles repel and unlike/opposite poles attract. The term ferromagnetic refers to the ability of a material to be magnetised. Magnets attract materials containing iron. Steel is a compound of iron with other metals. Therefore iron and steel are said to be ferromagnetic. There are two types of magnets; permanent and temporary

the current using the first circuit thus creating an electromagnetic..). So, if we turn on the first part of the circuit which allows the current to flow and consequently, electromagnet is produced in the circuit which produces a magnetic field around it - This electromagnet attracts the armature coil towards itself thus completing the circuit. Thus, the circuit is now completed and current flows through the entire circuit. Of course, if we want to simply stop the circuit at any time, we

extends in the east-west direction. They come from gigantic explosions on the sun, which sends streams of charged protons and electrons speeding towards Earth with a velocity of 200 million miles per hour. When these particles reach Earth’s magnetic field, they accelerate to about 134 million miles per hour then they are driven down towards the Polar

Jamie Sivertsen Physics 2 Instructor Eugine De Silva March 25, 2012 Project #1 The Use of Electricity and Magnetism in Future Transportation The dependence of our society on electricity is extremely obvious, but at the same time its easy to forget how dependent we actually are on it. Electricity plays a huge role in modern society that we do not even think about it. We take advantage of all the appliances at home and at the office, all the technologies we use to communicate, all

Insignificant gestures By Jo Cannon. Sometimes an experience or a meeting with a person makes a huge impression on your life. They could say something that you would think about for a while. Sometimes you meet someone who leaves a good impression and it might change your life. But what if the change is so big, that you can barely handle it? This story shows a great example of how an impression of another person can change your life, without you realizing it before it’s too late. We get to meet

two dimensional magnetic fields of magnets used in accelerators is discussed in terms of a harmonic expansion. The expansion is derived for cylindrical components and extended to Cartesian components. The Cartesian components are also described in terms of a complex field. The rules for transformation of the expansion coefficients under various types of coordinate transformation are given. The relationship between a given current distribution and the resulting field harmonics is explored in
