Gradient and shim coils designed with minimum power or stored energy can possess regions of high current density. A new method has been developed to spread out these areas of high current density, which should lead to lower peak temperatures. Here we test the heating properties of such minimax current density coils with and show that indeed the peak temperature is reduced in a model coil.
