In an electricity power starved country like India, Induction cooking may not be ideal. For example In Kerala there was flood of Induction cookers and the power requirement of the State shot up. Even though the Kerala government considered banning the sale of Induction cookers, they gave up the idea because it could not stand up in courts.
So instead they slapped a very high duty on induction cookers, like on cigarettes, to make induction cookers expensive so as to discourage people from buying it. So an induction cooker is best used as a backup in case of cooking gas getting over.
Below we explain with the use of pictures how an induction cooker works.
In the figure below, the picture on the right explains how an induction cooker works. AC current from the electric socket which is 50 cycles per second or 50Hz gets converted into very high frequency current, in the range of 1000s of cycles per second or KHz, and is fed into a coil placed just under the cooker burner surface. This creates a high frequency alternating magnetic field just above the induction cooker burner surface. These magnetic waves can only react with magnetic material like iron. Non-magnetic materials like Aluminium, copper or even our hand has no effect and no heat will be generated.
As an example you can see in the image on top left, the egg is being fried in an half cut frying pan on an induction cooker. The portion of the egg on the pan get hot and gets fried, but the portion of the egg which overflows on to the surface of the induction cooker remains cold and does not get cooked.
The induction cooker is very efficient because it is only the cooking vessel bottom that gets hot. It does not create hot gases like a gas burner. So with an induction cooker all the heat goes into the food being cooked and it does not heat the kitchen air or put a lot of carbon dioxide into the kitchen to make it stuffy and hot. Health wise the induction cooker is much better than a gas cooker, especially for people with asthmatic or breathing problems. Also the induction cooker is much safer than a gas cooker, it will not spread fire to your clothes or cause an explosion in the event of a gas leak.
The power consumption of induction cooker is high but only for short periods. While it is heating food, the power is on and off in a cyclic fashion and this is how the temperature of the food is controlled. The difference in running cost between using gas stove and an induction cooker is negligible, unless you're cooking for very long time every day. Both cooking gas and electricity are expensive in India. In a gas stove the gas burner wastes most of its energy as hot burnt gas and only about 25% of the heat in a gas burner is available to heat the food, whereas an electric induction cooker uses about 90% of the heat produced to cook the food. So depending on the cost per unit of electricity and the cost of the gas, one or the other could be cheaper, but the difference will be very small and negligible.
