Algae are considered as most ancient and important living organisms on earth. They occur in all conceivable biotopes influenced by environmental factors which affect their growth and distribution. Algae are extremely important ecologically as they provide 50-70% of the earth’s oxygen, and account for about half the food produced by photosynthesis on a global scale (John, 1994). With an innate ability to survive in the harshest of environments requiring meager natural resources and having been identified as a non-competitive food source, algae is now being touted as a solution for Clean Energy, Environment apart from being Food and Nutrition source. With algae related research programs gaining steady prominence, application of magnetic fields on micro-algae appears most promising.
