Magnetic Fields and Field Lines
Magnetic Fields and Field Lines - If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settles tangent to the ..

It is very easy to convert work into heat. For example, when two bodies are rubbed, heat is produced. However, for the conversion of heat into work, we require a device. This device is called heat engine..
Carnot Engine
Carnot Engine - In 1824, a French scientist N.L.Sadi Carnot, suggested an idealized engine which is called the Carnot engine, which has an intimate relation with the second law of thermodynamics. To understand the principle, let us consider an ideal gas taken in a cyli..
