Rapporteur's report: sources and interaction mechanisms.

This, the first session of the Workshop, focussed on sources of exposure to and interaction mechanisms of intense static magnetic fields. The four presentations dealt with (1) the magnetic fields produced by diagnostic magnetic resonance imaging systems; (2) the ways in which static magnetic fields can interact with matter, in particular human tissue; (3) the effects of magnetic fields on enzyme reaction rates; and (4) working practices for high-field magnet development.
