    Please tell me the weight of permanent magnet used in MRI airis 2

      According to the information I have consulted, the weight of the permanent magnet used in MRi AIRIS II is 15,700 kg.

      Yes, Airis 2 uses neodymium magnets.Almost all MRI permanent magnet components use neodymium magnets. Because compared to SmCo, Alnico, and ferrite magnets, neodymium magnets have much higher remanence (Br) and coercivity (Hci) than other permanent magnets. Good magnetic properties can reduce the footprint of MRI equipment.
      Similar examples include Siemens Magnetom C (0.35 T) and GE Signa Profile (0.2 T).
      However, it should be noted that as a semi open structure, C-shaped dipole magnets use large iron (or high permeability steel) for yokes to contain and guide the flux. Although the yokes greatly decrease fringe fields, they also increase the weight of the magnet assembly considerably, up to 16,000 kg
