Abstract
A simple and accurate method, using a search coil and a calibrated fluxmeter, is presented for experimental determination of residual flux of permament magnets of simple geometries. Applied to a small rectangular AlNiCo-VI magnet used variously, the method shows the importance of preventing accidental, or otherwise, demagnetisation of permanent magnets.
