WitrynaAn MRI scanner includes coils, a magnet, and wires that conduct current. In order to function, MRI scanners require a coolant that will give the magnetic coils in the scanner superconductive properties. That allows the electrical current to flow through the low resistance coils, enabling the generation of high-intensity magnetic fields.
