The term biodiversity describes the great variety of life on Earth. Biodiversity refers to the variety of living things, including plants, animals, and microorganisms. We don't know for sure exactly how many different organisms there are on Earth. However, scientists estimate that there are about 8-14 million (80 to 140 lakh) different species of organisms on this Earth. Some believe that the number is higher. But whatever the number, most of these organisms are unknown to us. Only 1.2 million (12 lakh) species have been identified and described so far, most of which are insects. This means that billions of other organisms are still mysterious and unknown to us. Origin of Biodiversity The unique characteristics of all sp

What is an induction stove?

In an induction stove, a cooking vessel is placed on top of a coil of copper wire with an alternating electric current passing through it. The resulting oscillating magnetic field wirelessly induces an electrical current in the vessel. This large eddy current flowing through the resistance of the vessel results in resistive heating.

How does induction cooking work?

The flow of an alternating current (AC) creates an electromagnetic field on an induction stovetop that excites the molecules in pots and pans that aren’t good conductors, like iron or steel. When these metal molecules are excited, they heat up quickly. They also cool down quickly.

You won’t see the stovetop glow red like you might a standard electric stovetop. And when the molecular connection between cookware and the stovetop is broken, the heat stops being produced.
