$170 0782022598 An induction hob contains a coil of copper wire underneath the ceramic plate, and when a cooking pot is placed on top an alternating electric current is passed through it. The resulting oscillating magnetic field induces a magnetic flux, producing an eddy current in the ferrous pot, which acts like the secondary winding of a More transformer. The eddy current flowing through the resistance of the pot heats it. To find out what an eddy current is, see below. Energy transfer with induction hobs is around 84 percent compared to around 74 percent for gas or ceramic electric so there are good energy savings. Safety is an important aspect too there is no naked flame so fire is extremely unlikely.
