Theoretical investigation of methods for the extraction of Copper intraocular foreign bodies with pulsed magnetic fields

The possibility to extract copper foreign bodies from the human eye with pulsed high field magnets is theoretically investigated. In principle it is feasible to succeed by a combination of a superconducting dc-magnet and a coil generating an asymmetrical pulsed magnetic field. Also sufficiently high attractive forces can be produced in not too small copper particles by rapidly shutting down a 10 MW Bitter-magnet. The medical limitations of the method are discussed.
