What exactly is the nature of the magnetic field produced by the device?

29 January 2023 1 9K Report

I'm confused! In 13CNMR spectroscopy, is 13C nucleus used in the device? What exactly is the nature of the magnetic field produced by the device? From carbon 12 or 13? And does it only stimulate the 13C in the sample or does it also stimulate the 12C in our sample? (Of course, the abundance of 13C is much less than 12C)
