Which kitchen equipment operates by the principle of magnetism?

The induction burner operates by the principle of magnetism, specifically through the use of electromagnetic fields. When an induction burner is turned on, it generates a magnetic field that induces a current in any ferrous (iron-containing) cookware placed on it. This current flows through the cookware and generates heat directly within the pot or pan, leading to efficient cooking.

This method is distinct from conventional cooking methods, such as those used by gas stoves, microwaves, and electric ranges, which do not rely on magnetic fields. Gas stoves use flame to produce heat, microwaves use electromagnetic radiation to excite water molecules in food, and electric ranges typically use electrical heating elements to produce heat without the direct involvement of magnetism. This efficiency and speed of induction cooking make it a unique and preferred choice in many modern kitchens, especially where precision and energy conservation are important.
