Systems, methods and apparatus are provided through which heat produced in the patient examination space by the power used to create electromagnetic fields in an MRI/MRS system is significantly reduced by coolant carried by one of two split connected concentric coil layers of one of two of the primary gradient coils used to alter the main magnetic field. The coil carrying the coolant is made of copper tubing. The second primary gradient coil is placed between the layers of the split primary gradient coil. Adjusting the number of turns in each layer of the split primary gradient coil adjusts the heat generated. The inductances and resistances of the two primary gradient coils are balanced by adjusting the gain of the coils.
