Magnetic field

2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field, thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

Revenge Magnetism Magnetism is a class of physical phenomena mediated by magnetic fields. All materials are in some way influenced by a magnetic field. The force between any two charged particles depends on the magnitude of the charge on each and the distance that separates them. In addition to electrical forces, there is a force due to the motion of the charged particles known as the magnetic force. Magnetic Poles Magnetic forces exert on one another similarly to electrical forces in that they

Human civilisation has dealt with magnetism for millennia, earliest evidence dating as far back as 1000 BC where the ancient Chinese civilisation discovered a naturally occurring magnetic ore, magnetite. This ore, commonly known as lodestone was used by the ancient Chinese as a geomagnetic compass, however, no one really knew what magnetism was at the time. For centuries on, we have had basic knowledge regarding electricity based upon static electricity found from rubbing amber and fur. However,

Objective: The objective in Lab 2 is to experiment with the relationship between current, force, and length of a conductor wire that has a current. This will be tested with magnets to create a magnetic field. Theory: Equation 1 below shows the relationship of force (F), current (i), length (L), magnetic field (B), and angle (Ɵ) for a current carrying wire. In this experiment, the angle between the wire and the magnets is 90⁰. This means that sinƟ=1 and can be eliminated. F=iLBsinƟ Equation

All magnets produce their own invisible magnetic field that’s unable to be seen with the naked eye, and each magnetic field interacts with other magnetic fields. Magnets are made of metals like iron ore, iron, or alloys, which is a mixture of metals, or of a metal and a nonmetal. Magnets only react with certain metals such as iron, steel, nickel, or cobalt. They have two poles, one of them is north pole, while the other is called the south pole. The opposite poles attract, while the same ones repel

conformed them to be used in everyday life. Magnetic levitation can be broken down into so many different topics such as magnetism and levitation, but there is a much deeper meaning to magnetic levitation. A magnet is an object that has a magnetic field. It can attract heavy objects such as iron and steel. A magnet can be in many shapes and sizes. The word magnet came from the elderly Cretan shepherd, Magnes. He supposedly found a rock that had a strong magnetic force. In the rock was large amounts of

Advantages 8 References 9 Magnetic Abrasive Finishing (MAF) Process Harry P. Coats first patented MAF in 1938. Although US originate this idea, most of later period development is done by USSR + Bulgaria. Japanese explore the technology for polishing purpose. Other countries in this field are: India, CIS, England, France, and Germany etc. Process details: • In MAP, w/p is kept between the two magnets & the air gap in-between the w/p & the magnet is filled with Magnetic Abrasive Particles (MAPs)

Magnetic Levitation and Propulsion through Synchronous Linear Motors MagLev technology is entirely different from any form of transportation in operation today, but the basic principles that lie at the foundation are not beyond the understanding of the beginning electricity and magnetism student. It is in the application of these principles to design and optimize an actual train that things get hairy. The basic idea has been researched since the mid-sixties, but it is only now that economically

Transportation is the process of which people get from one location to another; however, it comes at a cost. The price we all pay when we take a method of transportation comes in two forms. The first form is time and the second is a monetary value. In recent days it seems like the cost that correlates to transportation is rising. As raw materials like oil and coal become scares throughout the world the price for those materials increase as the demand increases. With the cost of raw materials increasing

by Pulsed laser deposition (PLD), metal organic chemical vapour deposition (MOCVD) and metal organic deposition (MOD). The Jc variations by pinning in high magnetic fields and angular range between the applied magnetic field and c-axis are discussed. High-temperature superconductors (HTS) are being developed for various electric and magnetic applications such as superconducting power cables, motors, generators,
