Coupling between conducting structures is one of the major design limitations for in-bore MRI equipment. Here we show how switchable plasma conductors can be used in a direct current (DC) MR coil for B₀ field manipulation. This can be applied in for example B₀ shimming, signal de-phasing or ultimately even gradient coil design.
