Permanent Magnet
 
A magnet whose magnetic field originates from permanently ferromagnetic materials (permanent magnets) to generate a magnetic field between the two poles of the magnet. There is no requirement for additional electrical power or cooling, and the iron-core structure of the magnet leads to a limited fringe field and no missile effect. Due to weight considerations, permanent magnets are usually limited to maximum field strengths of 0.4 T. The main disadvantages of a permanent magnet are the cost of the magnet itself and supporting structures and the varying changes in the magnetic field. Field homogeneity can be an on-going problem in permanent magnets.

the PoleStarâ„¢ N-10 is a compact, mobile MRI scanner that mounts to a standard operating room table. The magnets raise into position for imaging, but lower to make surgery easier, and the low magnetic field makes it possible to use many conventional surgical instruments.
When not in use, the PoleStarâ„¢ is stored in a nearby closet that allows the room to be used for conventional surgical procedures. The PoleStarâ„¢ N-10 is supplied with a fully integrated image guidance system that utilizes intraoperatively acquired images.
The successor, the new PoleStarâ„¢ N20 sets a new standard in intraoperative magnetic resonance imaging.
