Sunpentown Magnetic Induction Cooktop SR-1881WBecause magnetic waves induce heat directly into the steel or iron cookware directly, virtually 83% of the energy is transfered and not wasted. Of the energy introduced,.gas transfers about 40%, electric cooktops about 47%. for more info about how induction cooking work read below. Four Reasons to buy: SAFE: no flames, butane or burners! Eliminates the danger of gas jets and hot burners. The innovative design of the ceramic plate creates instant heat, but only to induction-compatible pans. FAST: no waiting time, heat is instantly transferred to the pan CLEAN: reduces pollution, fumes and offensive odor. Easily cleaned with a damp cloth CHEAP: induction heat costs 6 ~ 8¢ vs. $1.75 per hour for butane. Features: Dual functions: Cook & Warm Net Weight : 6 lb Safety Protections: Under Pressure Protection How Induction Cooking Works From the Michigan Technological University Induction cooktops have many advantages over other cooking methods, including efficiency, controllability, and safety. These advantages are easily explained by discussing how they work. Each hob contains one or more coils made of ferromagnetic material. When an alternating current is passed through these coils, a magnetic field of the same frequency is produced. If a magnetic-based pan is placed on the hob, the magnetic field induces a current in the pan. The internal resistance of the pan causes heat to be dissipated, following the Joule effect. Thus it is the pan itself, and not the cooktop, that heats up and cooks the food. Once the pan is removed from the cooktop, the energy transfer stops. The result is a flame-less method of cooking in which it is nearly impossible to start a fire by forgetting to turn off the stove. Parents won't have to worry about their child touching a hot burner because the cooktop surface remains cool. Changing cooking temperatures is achieved quickly because there is no wait for the hob to heat up, only the pan. Since there is no transfer of heat energy between the hob and the pan, less heat is lost into the air, resulting in a more efficient means of cooking, not to mention a more agreeable cooking environment.
