What physical action induces heat directly within the cookware's magnetic metal base?
Answer
Alternating current creating a magnetic field that induces eddy currents.
The fundamental process of induction cooking relies on electromagnetic principles. An alternating current flowing through a coil beneath the cooking surface generates a fluctuating magnetic field. This fluctuating magnetic field penetrates the base of compatible cookware, provided the base contains magnetic metal. This changing magnetic flux induces circular electrical currents within the metal itself, known as eddy currents. The inherent electrical resistance of the metal causes these induced currents to dissipate energy as heat directly within the pot or pan material, thereby heating the food without the cooktop surface needing to become the primary heat source.
