摘要：

The merits and limitations of a pulsed field system for the charcterisation of permanent magnets are discussed. The most significant limitation is the effect of eddycurrents which circulate in electrically conductive magnets. To minimise the errors due to eddy current flow a correction strategy is presented and supported by simulations.
