  2. NMR Safety Magnetic strength is described in Tesla or Gauss (1 T = 10,000 G) Earth’s magnetic field 0.6 Gauss at equator Refrigerator magnet 100 - 150 Gauss MRI medical scanners 0.3 - 1.5 Tesla (3 - 15,000 G) High field NMR magnet 200 MHz 4.7 Tesla (47,000 G) 300 MHz 7.0 Tesla (70,000 G) 500 MHz 11.7 Tesla (117,000 G) 800 MHz 18.8 Tesla (181,000 G) A superconducting magnet is always on!

  3. NMR Safety The magnetic field strength of a superconducting magnet decreases with increasing distance. Signs, chains, or tape on the floor indicate the approximate location of the 5 Gauss line around the magnet. • Do not enter the NMR lab if you have medical implants such as a pacemaker • Ferromagnetic items are attracted to the magnet. To be safe, assume all metal objects are ferromagnetic. • Jewelry, watches, tools, paper clips, staples, etc. • Devices with magnetic strips can be damaged • Credit cards, mobile phones, ipods NMR Safety Information.
