There are a variety of magnet types that can be used for MRI. Resistive and superconductive magnets are both:

Question

Quizplus · Accepted Answer

Resistive and superconductive magnets are both electromagnets, meaning they rely on an electric current to generate a magnetic field. This allows for more precise control over the strength and direction of the field, which is important for MRI imaging. Additionally, both resistive and superconductive magnets can achieve field strengths well above 3 tesla, making them useful for more advanced imaging techniques. However, they are not permanent magnets and typically require cooling systems to prevent overheating.
