A magnetic resonance imaging (MRI) scanner using a superconducting magnet. The magnet is inside the doughnut-shaped housing and can create a 3-tesla field inside the central hole. Superconducting magnets have a number of advantages over resistive electromagnets.
Most clinical magnets are superconducting magnets, which require liquid helium to keep them at low temperatures. Lower field strengths can be achieved with permanent magnets, which are often used in "open" MRI scanners for claustrophobic patients. [14] Lower field strengths are also used in a portable MRI scanner approved by the FDA in 2020. [15]
The superconducting magnet is one of the main sources to supply a homogeneous main static magnetic field (B0) for MR imaging. Normally it ranges from 1 T to 7 T. To obtain mobility for a conventional MRI scanner that uses a superconducting magnet to supply B0, it is placed in a trailer. [4]
powerful superconducting electromagnets used in maglev trains, magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) machines, magnetic confinement fusion reactors (e.g. tokamaks), and the beam-steering and focusing magnets used in particle accelerators; low-loss power cables
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
The lab develops technology, methodology, and applications at high magnetic fields through both in-house and external user activities. An in-house made 900 MHz (21.1 Tesla) NMR magnet has an ultra-wide bore measuring 105 mm (about 4 inches) in diameter, this superconducting magnet has the highest field for MRI study of a living animals.

The Magnex Scientific was a company involved in the design and building of superconducting magnet systems. In 2004 Magnex was bought by Varian, Inc.. The Magnet Technology Centre is the new headquarters for magnet manufacturing for Varian, Inc and is situated on the Oxford Industrial Park, 3 miles (4.8 km) north-west of the city of Oxford, England.
As described in the Physics of magnetic resonance imaging article, many MRI scanners rely on cryogenic liquids to enable the superconducting capabilities of the electromagnetic coils within. Although the cryogenic liquids used are non-toxic, their physical properties present specific hazards.
