Electromagnetism

 Topic Review on "Title": Magnetic flux: A measurement of the number of magnetic field lines passing through a particular area or surface. Faraday’s law: The voltage induced is directly proportionoal to the number of loops and the change in the magnetic flux.  It is inversely proportional to the time that this change occurs throughout. Lenz’s law: The induced emf always gives rise to a current whose magnetic flux opposed the original change in magnetic flux.  Thus, the induced current tries to maintain the level of magnetic flux. Electromotive force: A voltage that gives rise to a current flow.  This voltage can be induced or created by a changing magnetic field. Right hand rule, RHR: The fingers extend or curl in the direction of the magnetic field.  The outstretched thumb points in the direction of conventional current. Generator: A machine that produces electricity by a rotating coil of wire immersed in a stationary magnetic field.  This rotating motion could be obtained from a variety of sources.

 "Title" Tutorial Summary : Magnetic flux describes the number of magnetic field lines passing through a particular area.  This idea is similar to rain falling through a hula hoop.  Faraday’s law describes the induced electromotive force as the change in flux per amount of time. Lenz’s law describes the direction of that induced current.  Again, the right hand rule can be utilized.  A conductor moving through a magnetic field can also create an induced electromotive force.  These concepts are the basis for an electric generator.  Mechanical motion is converted into electric energy.
