    such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength. Another factor may be the size of the battery, because the stronger the battery is, the more power/voltage it contains which enhances the strength of the electromagnet. The way an electromagnet attracts other objects is also majorly…

    The mini torsion device that will be designed for this senior design project will apply a torsional load to a small cylindrical sample with a diameter of 5 mm or 6 mm. The device will need to fit under an optical microscope and will not be able to exceed the weight limits of the sample stage on the optical microscope so that Raman microscopy can be performed on the sample while it is under a torsional load. The device will also need to collect data and calculate the angle of twist of the sample.…

    Electronic system for identification of rebars in reinforced concrete. Abstract- In this paper non-destructive method is implemented in which magnetic self-designed sensor is used to detect position of rebar in reinforced concrete. During the renovation of old buildings it is necessary to locate rebar accurately to avoid damages in construction. This is achieved by Magnetic sensor which is made up of E-shaped core also primary and secondary windings. Due to presence of rebar output of sensor…

    placed in a rotating magnetic field and thus a rotating force can be attained. The rotor is a rotating conductor and is mainly produced in cage shape. The stator generates the rotating magnetic field. The rotating of the magnetic field is not achieved by mechanical principle rather by applying AC current to the stator. The AC current applied to the electro-magnetic results in the rapid changing of the polarity of the magnetic field and make it equal to a rotating magnetic field. Brush…

    Every vehicle has a number of electrical instruments. Each one varies due to the certain make and model of the vehicle with the different variations on the particular vehicle. Take a truck for instant it has a speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the…

    Stray current corrosion: Stray current is the current which occurs when conductors are placed between high magnetic or electric fields. Presence of stray currents over the PCB surface can generate corrosion problems. The below figure 5 shows severe corrosion damage to micro wave module for 24 GHz. This equipment is built in controlled conditions where water condensation is possible. After few hours of use, severe corrosion was seen on the surface. Figure 5. Stray current corrosion of a micro…

    hydrodynamics of a fluid is expressed in the form of conservation laws of mass, momentum and energy.The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well known, a conductor crossing magnetic field lines gives rise to an induced electric field, which causes an electric current in the conducting fluid. The following are the Maxwell,s equations ∇⋅D = ρcf ∇⋅B = 0 …

    Deadly, wicked, genius, brilliant, and wizard were all used to describe the bright and advanced mind of which belonged to Nikola Tesla. Too advanced for his time, Tesla’s ideas prove to be brilliant in today’s time. Tesla’s inventions and ideas lead to the advancement of society. Tesla believed that electricity could be found all around the world, and that it was easy to access. When Tesla came to America, he met an Indian Guru who taught Tesla about prana. The basis of prana is that energy…

    processes 5225FiTransport properties I. INTRODUCTION There has been significant recent work on Vlasov-Maxwell (VM) equilibria that are consistent with nonlinear force-free1–8 and “nearly force-free”9 magnetic fields in Cartesian geometry. Therein, force-free refers to a magnetic field for which the associated current density is exactly parallel, which is the definition we shall also use ∇×B=μ0j, j×B=0.These works consider one-dimensional (1D) collisionless current sheets, with Refs.…

    They’ll use a nail and a battery to create a magnetic field. It’ll turn the nail into a magnet. Students should be sure to write down their observations throughout the experiment. Students will wrap the center portion of the wire around the nail 10 times so that it forms a coil. They should have extra…
