Preethi Induction Cooktop�s stunning contemporary design and user friendly features is the outcome of diligent research and extensive consumer feedback. The result is a product that makes your everyday cooking fast and flexible. An Induction Coil beneath the Ceramic Plate produces a magnetic field that causes the electrons in the Vessel to vibrate and produce heat. The Vessel heats up the contents in it, while the cooking surface itself does not heat up.
