1. The history mvideo of the invention of the induction cooker induction cooker Modern, which recently appeared on the market, it appears, have a long and complicated backstory, dating back to the early 19th century. Phenomenon of electromagnetic induction, which is based on the action of induction cookers, was discovered outstanding English mvideo physicist Michael Faraday back in 1831 and played a huge role in the technical mvideo progress of our civilization. Sense Faraday law of electromagnetic induction is that the time-varying magnetic field generates a changing electric field or, in other words, the induction current. The essence of this physical phenomenon is understandable, of course, not everyone, but its practical application can appreciate every modern man. Phenomenon of electromagnetic mvideo induction underlies the actions mvideo of all generators, ie thanks to this discovery, humanity has learned to generate electricity and to develop the industry. Thanks to him, we can enjoy all the benefits of civilization: light, heat, wireless, numerous and varied appliances that make life comfortable and enjoyable. Thus, the discovery of Faraday formed the basis of technological development path of our civilization and has come a long way with her before electromagnetic induction found another way to use - in electric mvideo cookers. If the authorship of this scientific discovery does not cause any doubt, the question of who invented the induction cooker, remains open. However, it is significant is the fact that the world's first induction cooker was introduced in 1971 in the U.S. company Westinghouse Electric Corporation. Partly odnokonforochnaya plate was called "induction cooker coated with a cold." However, special interest and excitement, because of the high cost and not fully understood the principle of action, consumers have not caused. In 1987 in Europe, the German company AEG was presented the first induction hob. At that time, she also was not widely used, and used for many years, mainly in the professional restaurant business, and it's mvideo expensive equipment could afford only the finest restaurants.
2. Design and operation mvideo of the induction cooker And a few years ago appeared on the market improved, and therefore less expensive models available induction mvideo cookers, which are increasingly included in the daily life. But still, mvideo as once microwaves, cell phones, and many other achievements of modern civilization, induction cooker puzzling and fierce debate among potential buyers. Let's see how the induction cooker, what are its pros and cons? If you delve into the physical side of the question, it has become clear from the above that the work of induction cooker based on the principle of electromagnetic induction. Under the glass ceramic surface is copper coil. Electric current passing through the coil is converted into an alternating electromagnetic field that creates mvideo a changing electric field (induced current). Dishes with ferromagnetic properties, located on the cooking surface is a conductor with a deputy whip-circuit. Under the influence of eddy current induction when the electrons of the pan go into motion, resulting in the release of thermal energy, i.e. to heating. Thus, not heated hotplate and utensils directly itself and being in her food. In practical terms, this means a high speed liquid mvideo boiling or heating the pan, high heating efficiency - up to 90% (for comparison, the efficiency of heating on the gas burner is 60%, on the glass ceramic - 50%), cold burner during and after cooking ( perhaps only the presence of residual heat), and accordingly, guaranteed fast quality cooking any food and absolute safety. Prerequisite for the use of induction cookers, which many attributed to the downside - is the use cookware with ferromagnetic mvideo properties. In practice, things are not all that difficult. Often there is no need to buy expensive pots and pans new generation. Enough with a magnet to check your usual dishes: if a magnet sticks to the bottom, so you can safely use this cookware and induction hob. Based on the somewhat unusual, but such an effective mode of operation, induction cookers have a number of significant advantages over traditional electric with pancakes, vitrified or gas stoves.
3. The main advantages of induction cooker Economy. Induction cooker consumes several times less energy than a conventional electric, due to the fact that the burner is automatically adjusted mvideo to the diameter of the pan and heats only the required area. It not only saves energy but also your time. Due to the large power
