    1345 Words  | 6 Pages

    What is electromagnetism? Merriam-Webster states that “electromagnetism is magnetism developed by a current of electricity.” An alternative definition suggests that electromagnetism is a fundamental physical force that is responsible for interactions between charged particles which occur because of their charge. To fully understand how electromagnetism affects us, it is important to understand the basic foundation of electromagnetism. The field of electromagnetism was only six years old when Henry

    Electricity, magnetism, and electromagnetism are different but are all related. These topics are very similar in a wide variety of ways and are very fascinating. Each of theses natural phenomenons are field forces and the way protons, neutrons, electrons, and atoms react in these field are similar. The properties of these phenomena have been harnessed by humans to have practical uses in modern society. Electricity is a type of energy that come from charged particles that occur in two forms static

  • Criticism Of Electromagnetism

    943 Words  | 4 Pages

    Electromagnetism, other than its visible portion can be counterintuitive and hard to grasp because it is beyond the scope of our senses. It is noiseless, invisible and doesn’t smell. It is like a wave of energy surrounding any electrical device. Higher the frequency higher the energy it carries. It is probably easier to conceptualize sound waves because they are mechanical waves that are audible to us. Mechanical waves travel through a medium such as air, water and even solid walls. Electromagnetic

    Illustrate the operating principles of a permanent magnet DC motor Introduction A DC motor is a simple electromagnetism that converts mechanical energy to produce electrical energy. It relies basely on the fact that like magnet poles repels and unlike magnetic poles attracts each other. A coil of wire with a current running through it, and induces magnetic field generates aligned with the center of the coil. Theory of a DC motor When the current flow through a circuit with electrons, it induces

  • Magnetic Moment Experiment

    Besides of the property possessed by diamagnetic atoms or molecules, paramagnetic ones have unpaired electrons which lead to the major contribution to the overall magnetic moment in the direction of the applied field. This effect is obvious enough that can cancel the diamagnetic effect out. The microscopic magnetic moment of the electrons is quantized and they do Larmor procession in the external magnetic field which results from their motion affected by the external field as well as their spin around

    1232 Words  | 5 Pages

    Throughout his career, Tesla discovered, designed and developed ideas for a number of important inventions — most of which were officially patented by other inventors — including dynamos (electrical generators similar to batteries) and the induction motor. He was also a pioneer in the discovery of radar technology, X-ray technology, remote control and the rotating magnetic field — the basis of most AC machinery. Tesla is most well-known for his contributions in AC electricity and for the Tesla coil

    At that time it was still open whether electric motors should be rotating or reciprocating machines i.e. simulate a plunger rod of a steam engine. The first rotating device driven by electromagnetism was built by the Englishman Peter Barlow in 1822 (Barlow's Wheel). The first real rotating electric motor in May 1834 that actually developed a remarkable mechanical output power. His motor set a world record which was

  • Linear Induction Motor

    greater in a linear induction motor, more power is required and the efficiency is lower). The lack of an intermediate gearbox to convert rotational motion into straight-line motion saves energy. Both acceleration and braking are achieved through electromagnetism (increment of voltage or manipulation of electromagnetic field), linear induction motors are much quieter than ordinary motors. Linear induction motor are also very responsive since it is not consist of mechanical part. It’s high production cost

It is of vital importance for engineers to know motors so that they can choose the right one for their requirement. 1.1 PRINCIPLES OF OPERATION OF THE DC MOTOR In any electric motor, the basic theory by which all DC motors operate is electromagnetism. There are two states which are compulsory to produce a force

    Question 1 1. Societal orientation is when an organization considers short and long term issues when it comes to satisfying customers’ needs and want. They take in consideration the customers and societies well-being. Once they have identified the need and wants of the customers they then put strategies in place in order to please the customer to make them feel satisfied. An example of societal orientation is when an organization manufacture provided smash and grab windows in order to make the customer

  • Static Discharge Advantages And Disadvantages

    746 Words  | 3 Pages

    3. What is ElectroStatic Discharge(ESD) and how do I prevent it? It is the release of static electricity when two objects come into contact with each other. ESD first needs a build-up of electrostatic charge. This occurs when two different materials rub together and create friction. One of the materials become positively charged and the other becomes negatively charged. The positively charged material has a electro-static charge. The heat of a ESD is extremely hot. When a charge is released into

  • Steam Engine Invention

    In addition to the discovery of latent heat being used for calorimetry, latent heat also brought about changes to the steam engine. As previously mentioned, Joseph Black worked closely to James Watt, inventor of the steam engine, doing several experiments together; their teamwork is what truly what gave rise to the discovery of latent heat. So although Joseph Black did not directly invent the steam engine, his discoveries in the lab is what made the industrial invention possible (Cooper, 1999). A

    Electric Motor An electric motor is a device that converts electrical energy into mechanical energy. In today’s life, electric motors have numerous applications including in homes, commercial buildings, and manufacturing industries. An electric motor works on the principle of Ampere’s law which states when a wire is carrying an electric current, it generates magnetic field around itself. In other words, an electric motor is able to generate motion by use of magnets and therefore its whole operation

  • Conventional Capacitors

    Conventional capacitors are made up of two conducting electrodes which are further separated by an insulating dielectric material. Opposite charges build up on the surfaces of each electrode, when a voltage is applied on capacitor. The charges are separated by the dielectric, thus establishing an electric field that allows the capacitor to store energy. Capacitance C can be defined as: (1.1) Where

    4.1 TYPES OF DC-DC CONVERTER DC-DC converter is an electrical circuit whose main application is to transform a dc voltage from one level to another level. It is similar to a transformer in AC source, it can able to step the voltage level up or down. The variable dc voltage level can be regulated by controlling the duty ratio (on-off time of a switch) of the converter [8]. There are various types of dc-dc converters that can be used to transform the level of the voltage as per the supply availability
