Wed 11/15: UC Berkeley physics H7B: Electricity & Magnetism

Professor Irfan demonstrated eddy currents in the electricity & magnetism lecture. He supercooled an aluminum ring with liquid nitrogen, and used a solenoid to project it so hard it hit the ceiling. He shot a room temperature, copper ring a few feet into the air but wouldn't supercool it because it would be such a good conductor that it could cause damage when it flew into the air.
