Question
State types of commercial generators.

Answer

Electrical energy is generated commercially in commercial generators. Different types of generators are as follows.
(i) Hydro-electric generator :
The mechanical energy required for rotation of armature in this generator is obtained from water falling from a height. ex dams.

(ii) Thermal generators :
Water is heated to produce steam using coal or other sources. The steam at high pressure produces rotation of armature.
(iii) Nuclear power generators :
Instead of coal, if nuclear fuel is used then such generators are called Nuclear power generators.

Two bar magnets are placed close to each other with their opposite poles facing each other. In absence of other force the magnets are pulled towards each other and their kinetic energy increases. Does it contradict our earher knowledge that magnetic forces cannot do any work and hence cannot increase kinetic energy of a system?
