Electromagnetic compatibility (EMC). Environment - Low frequency magnetic fields in various environments1 Scope Interest in magnetic fields has been stimulated in recent years by concern over the physiological effects they may have on humans and animals and the deleterious effects they have on the performance of some electrical equipment, particularly video display units. Investigations have yielded results which are presented in this report as reference values. NOTE 1 The European Union EMC Directive has prompted magnetic field measurements,
