To understand why some pots are not suitable for induction hobs, first, we need to see the differences between regular and induction hob. Here's how both types work:
Conventional stoves heat pots and pans by contact. The electric heating elements of conventional stoves generate heat, and this heat is transferred through contact to the base of the pot through a process known as thermal conduction.
Induction hobs, on the other hand, do not generate heat. They have a coiled wire just below the ceramic surface that generates an oscillating magnetic field.
This means that the pans you use must be made of a magnetic material to work with this system. The induction plate will cause the electrons in the magnetic material to move, creating an electric current. This current generates heat in the vessel.
If you put your hand or a glass pot on an induction hob, neither will get hot because they are not magnetic.
Magnetic materials that are suitable for induction hobs are cast iron, steel and magnetic stainless steel (it should contain some iron).
Ceramic coated and enameled pots are also suitable because there is a magnetic material hidden in the ceramic layer.
Are your pots suitable for such a stove?
Take a magnet from your refrigerator and hold it near the bottom surface of the cooking vessel. If the magnet sticks to the base, the pot is magnetic and will therefore work with an induction hob.
