NURSYAHIRA ABD HAMID ASSIGNMENT 1 Explain the concept and purpose of the geochemical‚ gravity‚ electromagnetic and magnetic surveys. 1. Concept and purpose of geochemistry Petroleum geochemistry has played an important role in many areas of exploration and production for fossil fuels. Many of the more recent developments can be seen to have developed in parallel with developments in analytical chemistry such as gas chromatography and gas chromatography−mass spectrometry. For the past two decades

| 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

global warming was created The production of electricity * In 1831‚ Michael Faraday discovered electromagnetic induction‚ which lead to the development of the electrical generator * The generator consists of a rotating coil or wire in a magnetic field * Most power stations burn fuel to obtain this energy. * Nuclear Power stations‚ hydroelectric power station‚ wind power‚ tidal energy are used to save non renewable energy. Electrostatics * Electrostatic is the study of bodies

Headphones would not have been invented had it not been for the revolutionary combination of beneficial concepts in both electricity and magnetism. Not that much of a scientific fiction anymore‚ hovering vehicles seem achievable through magnetic levitation using Lenz’s law‚ as demonstrated by the already existing maglev trains in Japan‚ South Korea‚ and China. It is true that power supply is problematic and expensive. However‚ it is a decent beginning that shows the possibility of having

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 dl and r. According to Biot-Savart’s law‚the magnetic field induction

Magnets. How do they work? How does the number of coils affect electromagnetism? Hypothesis: When there is a flow of moving electrons‚ a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount

has been modified to function as an amplidyne. INTRODUCTION A generator is a machine that converts mechanical energy into electrical energy by using the principle of magnetic induction. This principle is explained as follows: Whenever a conductor is moved within a magnetic field in such a way that the conductor cuts across magnetic lines of flux‚ voltage is generated in the conductor. 1-1 The AMOUNT of voltage generated depends on
