Magnetically induced torque

On an object with a magnetic moment (e.g., due to its geometric shape), the static magnetic field of the MR scanner induces a torque. For an implant to be considered MR safe, this torque should be smaller than the equivalent gravity torque, because gravity of the implant has been empirically shown to be continually tolerated by the body.

MR:comp has been officially accredited to conduct tests of magnetically induced torque according to ASTM F2213.
