Electromagnetic Induction
... the armature turns, the wire loops cut through the magnetic field lines, inducing an EMF. The EMF, commonly called the voltage, developed by the generator depends on the magnetic induction, B, the length of wire rotating in the field, L, and v, the speed of the loops perpendicular to the magnetic fi ...

... The transport of small polarons in an ionic solid may take place by two different mechanisms. At low temperatures small polarons may tunnel between localised sites in what is referred to as a narrow band. The temperature dependence of the mobility is determined by lattice scattering and the polaron ...

... is more than one way to make an electric field. You can make an electric field with electric charges, as around a point charge or between charged capacitor plates, but also an electric field accompanies a time-varying magnetic field. Wherever there is a time-varying magnetic field, there is also an ...
