MIT Physics | Walter Lewin: The Electric Shield (Faraday Cage) Witness one of the most electrifying demonstrations in physics as Professor Walter Lewin steps inside a wire mesh cage and subjects himself to hundreds of thousands of volts. This unforgettable lecture illustrates the powerful concept of electric shielding, or the Faraday cage effect. Discover the fundamental principle of electrostatics that explains why the electric charge resides exclusively on the outer surface of a conductor, lea

Conservation of energy demo This is an impressive video by Professor Walter Lewin (MIT), in which he brilliantly demonstrates the conservation of mechanical energy, utilizing a swinging pendulum bob. When the pendulum is released from rest, it can never reach a higher position then its initial height. | Fadhel Mahdi
