Resumen
Method of remote detection of resonant labels.The present invention permits the simultaneous and remote detection of objects fitted with suitable labels by the application of magnetic fields using permanent magnets. The said labels are characterised in absorbing electromagnetic radiation of a particular frequency called the resonant frequency which depends on the intensity of the static magnetic field to which they are submitted. The said static magnetic fields, when applied by permanent magnets, have a high power and occupy a small space. This permits only a small number of labels, independent of their orientation, that have a resonant frequency corresponding to the high field to be detected.
