Magnetic field

creates magnetic domain where the electron aligns and with more than 10 coiling, it wouldn’t produce a difference of electricity. Same size of battery…

1.2. Cones Speaker cones vary in size and shape as well as the material they are made of. They range from original Rice and Kellog design-paper cone, through Kevlar and carbon fibre, metal (aluminium) and a variety of composites, each manufacturer employing different materials suited to providing the best efficiency and linearity. First of all they wanted to achieve manufacturing consistency since wood is not a homogenous substance and tends to vary from one form of timber to another, even…

sensor are determined by the physical variable they sense and are categorized in; Electrical: current, voltage, resistance, capacitance, inductance, and charge; Chemical: chemical concentration, composition, and reaction rate; Magnetic: magnetic field intensity, flux density, and magnetization; Mechanical: displacement or strain, level position, velocity acceleration, torque, pressure and flow rate; Radiant: electromagnetic wave intensity, wavelength, polarization, and phase;…

Electricity wasn’t invented it is already occurred in the nature. It was just discovered by Benjamin Franklin. His experiments (famous kite experiment) helped in building the connection between the electricity and lightning. In his experiment with kite included a kite with the key tie to the end of kite, which is connected to the Leyden jar. When the lighting struck the kite, the electric current travel down the string through the key and into the Leyden jar. We wonder that “what is there in…

1. Existing Knowledge- Based on prior knowledge, the Sulfur and Iron powder can be separated by using a magnet. The known fact is that the Iron particles can be attracted to the Magnet because of the attraction of the opposite charges. The Magnet will pull and attract the Iron and leaving the Sulfur behind. The separation of Sulfur and Iron powder is successfully accomplished because of the property of attraction. Since Iron is a metal, it has a positive charge and one side of the magnet has a…

are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that coil with wire, it will produce a strong electromagnetic field.…

single, flexible strand or rod of metal which is typically cylindrically-shaped. The core applications of wire, both single- or multi-stranded wire, are to withstand or carry mechanical loads in construction sector, whereas in electrical and electronic field are used to transmit electricity and telecommunications signals. For examples, from view of construction, wires are either braided or fixated together to form a bundle of strands, namely multi-stranded wire or conventionally known as cable,…

Turbulence May Spawn Monster Magnetic Fields discusses a lab experiment that aimed to investigate the mysterious and powerful properties of magnetism in space. Magnetic waves are extremely prominent in our universe, which consists of dense galaxy clusters and vast voids of space separating these clusters. While it seems obvious magnetism would be present in the various galaxy clusters, as they are active regions of space, astronomers have also discovered a very strong magnetic presence in the…

How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…

AC stands for alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the…
