ON THE ELECTRODYNAMICS OF MOVING BODIES By A. EINSTEIN June 30‚ 1905 It is known that Maxwell’s electrodynamics—as usually understood at the present time—when applied to moving bodies‚ leads to asymmetries which do not appear to be inherent in the phenomena. Take‚ for example‚ the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet‚ whereas the customary view draws a sharp distinction

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

| Maximizing the Range and Power of Inductive Coupling | | | Isaiah Anderson | 1/11/2013 | | Abstract In this project I studied how an electrical current moving through a coil of wire can generate an electric magnetic field and power an electrical load connected to a similar coil of wire. This experiment has been performed before but the goal of this project was to increase the efficiency of the circuit. In this experiment multiple different coils were tested in order to find

BIOT-SAVART’S LAW OR AMPERE’S LAW FOR CURRENT ELEMENT Biot-Savart’s law deals with the magnetic field induction at a point due to a small current element. Current element A current element is a conductor carrying current.It is the product of current‚I and length of very small segment of current carrying wire ‚dL. Let us consider a small element AB of length dl of the conductor RS carrying a current I. Let r be the position vector of the point P from the current element I dL.and θ be the angle

Electricity was first researched by Thales of Miletos around 600BC. He conducted a few experiments on static electricity in which he believed that friction made amber become magnetized. Other than the fact that people knew that eels produced electric shocks‚ electricity was little more than an intellectual curiosity for over 2000 years. Until 1600 when someone from England discovered the lodestone effect when amber with static would attract small objects towards it. In the 18th century‚ Benjamin

Overview Of Neuron Structural and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals‚ and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically‚ neurons are five to six orders of magnitude slower than silicon logic

I plan to pursue a degree in Computer Engineering with an emphasis in technology engineering. I have been interested in this field from the time I work fixing my brothers bikes and mine and‚ most recently days helping my father after school. Just working with my hands is something that gets my attention and enjoy many new things. This is why I believe that computer engineering is the right career for my future. Ever since I was in seventh grade electronics has been one of my favorite subjects. I

Investigating Electromagnets Aim: The aim of the experiment is to investigate what affects the strength of an electromagnet. Hypothesis: The more coils and electricity the more powerful the electromagnet becomes. Prediction: When the voltage of electricity is increased I think that the nail will have more magnetism allowing it to attract more paper clips‚ because with more voltage going through the circuit‚ it can then make the electromagnet stronger. Variables: Independent The independent

Analysis of longitudinal end effects in a Single Sided Linear Induction Motor using Stream Function approach Abstract-This paper presents the analysis of longitudinal end effects in a single sided linear induction motor leading to the calculation of fields and currents in the rotor sheet and propulsion and levitation forces. Such problem can be tackled by vector potential or stream function approach. The present paper adopts the second approach. A second order partial differential equation has
