2 Integral form of Maxwell`s equations and time

... It is very important to note that in order to arrive at a non-vanishing motional induction term, the contour of the surface S has to be moving. That is, if the contour is fixed and S(t) is still a function time there will be no motional induction. Physically the contour of the integral (circuit) has ...

Induction cooking heats a cooking vessel by magnetic induction, instead of by thermal conduction from a flame, or an electrical heating element. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved.In an induction cooker, a coil of copper wire is placed under the cooking pot and an alternating electric current is passed through it. The resulting oscillating magnetic field induces a magnetic flux which repeatedly magnetises the pot, treating it like a lossy magnetic core of a transformer. This produces large eddy currents in the pot, which because of the resistance of the pot, heats it.For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferromagnetic metal such as cast iron or some stainless steels. However, copper, glass, non magnetic stainless steels, and aluminum vessels can be placed on a ferromagnetic interface disk which functions as a conventional hotplate.
