Principle and Characteristics
Working Principle
An induction hotplate works by heating
a receptacle using the currents induced
by a magnetic field. When an electric
currentpassesthroughacoil,itgeneratesa
magneticfield.Onaninductionhotplate,this
magneticfieldistheninducedintothebase
ofthereceptacle.Foucaultcurrentsofvery
lowintensitypassthroughthebaseofthe
receptacle.Despitetheirlowintensity,these
currentsgenerateheatinthereceptacleas
they passthrough it. The principle behind
theinductionhotplate isto multiplythese
Foucault currents while changing the
directionoftheveryhighfrequencyfieldin
ordertoheatthebottomofthereceptacle.
The heating process is instantaneous,
becauseassoonasthecoilpowersupplyis
activated,thereceptacleisheated.Foodis
thenheatedthroughcontactwiththebase
ofthepan.
For the induction method to function
properly, the cooking utensil must be
ferromagnetic. (See details in the section
