MRI Magnet

Superconducting MRI magnets are advanced medical devices that generate the strong and homogeneous static magnetic fields essential for magnetic resonance imaging. These magnets are typically made from superconducting materials like niobium-titanium (NbTi) or niobium-tin (Nb3Sn), which can carry large currents without resistance when cooled to very low temperatures, around 10 Kelvin, using liquid helium . 
They produce magnetic field strengths ranging from 0.2 to 3.0 Tesla in clinical practice, with research magnets reaching up to 7 Tesla or more . The main characteristics of these magnets include their type, field strength, and homogeneity . Superconducting MRI magnets offer advantages such as low energy consumption, compact coil structure, stable current and magnetic field, and good field uniformity . They are also continuous in operation and are equipped with safety systems to handle potential loss of superconductivity, known as a quenching event, which can lead to rapid boiling of liquid helium . These magnets play a critical role in providing the high vacuum conditions necessary for advanced imaging and diagnostic procedures in the medical field .
