Introductory NMR and MRI with Paul Callaghan

In this excellent series of videos, Paul Callaghan demonstrates the basics of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). Note that he is using a table-top NMR system that does not have a static B0 field. Rather he creates a “pre-polarizing pulse” prior to each experiment. This is achieving the same thing as B0 in a superconducting magnet.
