Do you have the slightest idea about how technologically advanced ancient Hindu civilization was?
Make sure to read the article. 1000 years back, when Mohamed Ghazni plundered Somnath Temple, he found a Lingam revolving above the pedestal without any support like this. Probably the ancient Hindus knew these physics well.
Now, see this video and you’ll get an idea about the technology behind it.
Now, Let’s understand magnetic levitation:
Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields.
Maglev trains use magnetism to levitate above the tracks on which they travel. They are faster, more efficient, and more environmentally friendly than modern wheeled trains. It may be that one day soon, maglev technology will be commonplace throughout the world.
