How do induction cooktops work ?
During induction cooking you heat a cooking vessel by electrical induction, rather than thermal heating by conduction via a flame, or an electric heating element. But, you must remember that your cooking vessel must have a magnetic base. The cooking vessel must be made of ferromagnetic metal or contain it. This could be cast iron or stainless steel. Here, heat comes from within the pan, thus making your cooking method, more efficient. Copper or aluminium pans may not work unless they have magnetic layers down below. The best way to check is using a small magnet, to see if it sticks to the base. Let’s get into some more details. An induction hob has a copper coil, under a ceramic plate. When you put a pan on top of the heated surface, an alternating current is passed through it. This results in an oscillating magnetic field inducing a magnetic flux, which produces an eddy current in the ferrous pot. This acts as a secondary winding of a transformer. This eddy current flowing through t
