Superconducting magnets use a special wire which loses all resistance when cooled to -270 degrees Centigrade. This requires liquid helium to surround the magnet wire. Current is applied to the wire during instillation, which generates the magnetic field as it flows. Superconducting magnets are normally FULLY ENERGIZED at all times..

Safety Background. The MRI scanner is a very large and powerful magnet. Most clinical scanners are 1.5 - 3 Tesla scanners. 3 Tesla = 30,000 gauss. Earths magnetic field ~ 0.5 gauss. MRI SAFETY. Magnetic Resonance Imaging (MRI) is one of the most powerful medical diagnostic technologies, combining strong magnetic fields with powerful computer image processing.. Safety Background.

The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. Magnetic Resonance Imaging (MRI) is a painless and harmless examination. This type of scan uses a powerful magnetic field and radio frequencies. It does not use Xrays.
