How does an induction cooker work

How does an induction cooker work-

Induction cookers are based on the principle of electromagnetism effect. The cooking utensils (usually made of glass-ceramic) are placed under the cooking surface on a coil made of copper wire. Alternating current in induction cooking flows through a coil made of copper wire, and produces a magnetic field. The cooking utensil placed above the cooking surface gets inspired to create a magnetic field under the influence of this alternating current. The current flowing through the cooking vessel also produces a resistive heating, which gives the heat needed to cook the food. Unlike the case of a gas stove or an electric stove, in which the heat around the cooking surface is heated, the induction cooker only heats the surface. This causes less wastage of heat and energy, due to which the kitchen area remains relatively cold. 

Advantage induction cooker-

1.They are quite safe to use due to control systems and other security features.

2. Easy cleaning and management required 

3. Low energy consumption that is friendly to the environment 

4. Heat dissipation is minimal, which in turn increases efficiency and also keeps the kitchen cool. 

5. Faster than conventional gas stoves.

6.Use of temperature controllers and timers makes them easy to use.

 Disadvantage induction cooker-

1.Expensive than regular cook pots

2.Require special cookware

3.Cannot cook food when there is no electricity

4.Food such as chapatti / roti which requires an open flame in cooking, cannot be cooked on an induction cooker.

5.Induction cooker only works on flat bottomed utensils, it has difficulty in working with very large or very small utensils.
