Measurements of the trapped flux (rcmanent magnetism) in polycrystalline YBasCusO, in the range 15-50 K show that at low applied field pulses, flux is trapped in the intergrain voids. A detailed measurement of a map of the remanent field over the whole surface of the sample shows that at very low fi
