Fun with an MRI magnet

In honor of MRI Safety Week, four simple demonstrations of induced magnetism in non-ferromagnetic objects, and one demonstration of an unlikely magnetic object. Apologies for the awful sound quality, it's a new MRI facility and we don't yet have all the sound-proofing up to eliminate the echoes. And we were in a hurry. First, a copper ring is accelerated under gravity, inducing a current and an opposing magnetic field in the ring that makes it float down rather than fall. Next, an aluminum ball c
