It it the generic term for a coil of wire used as an electromagnet. Solenoid It is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets He is a german physicist formulated a law that explains the direction of the induced current in a conductor. Heinrich Friedrich Emil Lenz Defined as the electric potential produced by either electrochemical cell or by changing magnetic field. Electromotive force A french physicist and mathematician who was one of the founders of electromagnetism. and the one who gave the right hand rule. Ampere It is a property of an electrical circuit in which an electromagnetic force is induced or produced by a changing current in a coil. Inductance An english physicist and chemist, discovered electromagnetic induction, the principle behind the electric transformer and generator, by observing that a current flow in a wire that is moved through a magnetic force. Michael Faraday The study of the relationship between electricity and magnetism. Electromagnetism He is a danish physicist and chemist who discovered that electric currents create magnetic fields Hans Christian oersted the term when the inductance happens between two nearby coils. mutual induction It is the amount of work needed to move an electric charge from its reference point. electric potential the symbol for electric potential. V it is the symbol for electric potential energy. J the ratio of work done in or by moving charge from a point of lower potential to higher potential. Electric potential difference it it the region around the charge when an electric force is detected. Electric field it is the force applied at a given distance. work the unit for electric potential energy. joule
it is the energy needed to move a charge against an electric field. electric potential energy it is the unit of charge C Coulomb it is the unit of electric field N/C Other term used to describe electric generator dynamo it provides the necessary amplification to convert a small current into a larger one. Amplifier a device that uses electromagnetism to change electrical energy into mechanical energy Electric motors in his name was derived from the term galvanometer luigi galvani this is an electromagnet which is placed in the magnetic field of a permanent magnet. it is made up of many loops Armature it converts mechanical energy into electrical energy DC generator other term for AC generator alternators this type of transformer can increase the voltage step up transformers it connects the commutator to the current source brushes a device that changes the voltage current in an AC circuit using electromagnetic induction transformer these power plants use the energy from radioactive materials like uranium or plutonium Nuclear Power Plants utilizes the wind energy Wind Power Plants a rotary engine that converts the energy of a moving stream of water or gas into mechanical energy Generators utilize underground water heated by molten rocks Geothermal Power plants used to convert the power of flowing water Hydraulic Water turbines these types of power plants use coal, natural ga and oil Fossil fuel power plants
a device used to measure electric current Ammeter It is a german word which means “ pipes “ Rohr It states that the emf induced in a loop of wire is proportional to the to the rate of change of magnetic flux through the coil Faraday’s law It is a material that when used as a core of an electromagnet retains its magnetism after the current is cut off Iron it is a measurement of the total magnetic field which passes through a certain area Magnetic flux It is the study of magnetic field as well as their effect on materials Magnetibiology It is the term used to describe strong magnetic materials Ferromagnetic a device used to measure magnetic flux Magnetometer It is a substance that keeps their magnetism for a long time Permanent magnets he is the one to make quantitative study of the force exerted by magnets Charles Agustin de Coloumb it is a region where group of containing billions of atoms line up Magnetic domain he is the one who discovered and patented the rotating magnetic field Nikola Tesla A german physicist, one of the inventors of the first electromagnetic telegraph Wilhelm Eduard Weber It is the unit for the strength of magnetic field T two permanent magnets on the side of the armature AC and DC motors a simple circuit that triggers a sound on the completion of circuit by pressing the button Electric doorbell the coil that is connected to the alternating current source Primary coil a device that can reduce the voltage and increase the current Step-down transformers
a component consisting of diodes which allow the current to flow through them in only one direction and filter out the opposing current produced Diode It stores chemical energy which also convert that energy into electrical energy Battery A device that utilizes electromagnetic induction to change the voltage and current in an AC circuit. Transformer
