| Charged
particles moving in a magnetic field
in this demonstration particles are entering the region of the magnetic field with their velocoties being
perpendicular to the magnetic field lines. In such a situation the magnetic force serves to move the particles in a circular path |

| Current testing
electrical currents are generated in a conductive material by an induced alternating magnetic field. The electrical currents are called eddy currents
because they flow in circles at and just below the surface of the material. Interruptions in the flow of eddy currents, caused by imperfections, dimensional
changes or changes in the material's conductive and permeability properties, can be detected, a tip |

| Faraday's
magnetic field induction experiment
after discovering electromagnetic induction, Faraday began to test a hypothesis on magnetic fields and energy
currents, which is demonstrated in this tutorial showing a galvanometer connected to a wire wrapped paper cylinder |
| Faraday's
electromagnetic induction experiment in 1831, Michael Faraday made his discovery of electromagnetic induction with an experiment using two coils of
wire wound around opposite sides of a ring of soft iron |

Hysteresis Magnetic hysteresis is an important phenomenon and refers to the
irreversibility of the magnetisation and demagnetisation process. When a
material shows a degree of irreversibility it is known as hysteretic |

the area of a coil in a constant magnetic field |

Inductance Applet This applet shows how EMF is induced in a loop by changing
the magnetic flux through the loop |

|
Lenz
law This (Quicktime) animation shows that the magnetic field produced by an
induced current creates a flux that opposes the change in flux that produces the
induced current |
|
Lenz
law Electromagnetically induced current always flows in such direction that
the action of the magnetic field set up by it tends to oppose the very cause
which produce it |
|
Lenz
law |
| Lenz's
law
this interactive tutorial illustrates the directional relationships between induced magnetic fields, voltage, and current when a conductor is passed
within the lines of force of a magnetic field, an electric current induced by a changing magnetic field will
flow such that it will create its own magnetic field that opposes the magnetic field that created it |
