Abstract :
A method for the rapid measurement of low coercive force materials (e.g. high permeability nickel iron alloys) has developed by modifying the NPL vibrating coil magnetometer to improve its sensitivity and by providing a magnetic shield to reduce the effects of the ambient magnetic field. A comparison of the results has been made with those obtained by the traditional ring method
