0.9968 and for two magnets the r^2 value is 0.9773. These r^2 value is suggesting that the data collected for one magnet is more accurate than for two magnets as 0.9968 is closer to 1 therefore saying that voltage produced per amount of shakes is directly proportional which is proving the Faraday Law right. The line with two magnets is steeper because by increasing the length of the magnet you are increasing the length of the magnetic field that passed through the coil of wire at one particular moment which increases the voltage produced. This is advocated to be correct as seen in the graph, the slope of the graph shows the voltage produced. With one magnet it can be seen 0.4304 V is produced when…

causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law, discovered in 1831 by Michael Faraday, this alteration in flux produces electromotive force (EMF) and eddy currents inside the…

rotation, if A leads B then disk is rotating in a clockwise direction and if B leads A then disk is rotating in counterclockwise direction. Output of encoder is equivalent to 1,024 pulses per revolution. Following formulae is used to calculate linear distance travelled by disk, Linear distance covered = (output of encoder *3.1416*diameter of disk)/PPR of encoder Fig. 2. Rotary Encoder Fig. 3. Rotary encoder output B. Magnetic Sensor Magnetic sensor is designed which works on the principle…

In the case of zero scalar potential, the result of the calculation is to give a distribution function that is not a solution of the Vlasov equation as it is not a function of the constants of motion only. In essence, an additional exp(−r2) factor is required in the DF to counter exp(r2) terms that manifest by completing the square in the integration. The physical cause here would appear to be the inertial forces associated with the rotational bulk flow. If one assumes a non-zero scalar…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

work was necessary… it was emphatically not why he had decided on a scientific career” (Frank 2). Faraday was interested in this work, but he knew that there were more important discoveries to be made. When the two returned from their tour, Faraday started to run in some opportunities to exercise some of his ideas. In 1821, a close friend of Faraday’s, Richard Phillips, asked him to survey the activity of the recently discovered idea of electro-magnetism for his new book. While doing this, he…

quantity in crossing interface from 1 to 2. The boundary conditions on the velocity vector for inviscid fluid flow are simple because here, the normal component of the velocity alone need to be continuous where as for viscous fluid flow both the normal and tangential components of the velocity must be continuous and hence the boundary conditions are given by n ̂ .[q ̅ ]=0 (1.13) n ̂×[q ̅ ]=0 (1.14) If J ̅,ρ_e denote surface current and surface charge density respectively, then…

commutator is used. A commutator is a metal ring with splits that periodically reverses the electric current (Woodford). The working of an AC generator is based on electromagnetic induction which means that whenever a flux passing through the circuit changes, an EMF is induced in it and a current begins to flow (R.Nave, AC Motors and Generators). A generator consists of: 1. A magnet with concave cylindrical poles that create a radial magnetic field. 2. An armature which is a soft iron core…

Faraday’s experiments such as the motor principle demonstrated that an electric motor converts electrical energy to mechanical motion expanded the research already done by Ampere and Oersted. He also established other principles including those of the transformer, generator, and electromagnetic induction. James Maxwell developed an electromagnetic theory of radiation which he proposed that the ether transmitted electromagnetic radiation as a wave through space at the speed of light. The…

wire; a toroidal metal electrode (E). In order to build a 3-meter Coil and its components were also used PVC pipes, wood to build supports, lightning rods and screws. The operation cycle of the Coil starts with the transformer increasing the standard Brazilian voltage of 120/220V to 15.000V. This voltage is used to charge the capacitor bank (C1) until the level when it reaches the breakdown voltage of the spark gap, enabling currents to flow rapidly back and forth between C1 and the coil,…
