In this work, we measured eddy currents for a very high order B₀ shim system. The eddy currents were measured using two methods: a low-resolution B₀ mapping sequence and a NMR field camera. The high temporal resolution of the field camera allowed the eddy currents to be corrected using a digital pre-emphasis setup.
