A Method to Measure Permeability of Permalloy in Extremely Weak Magnetic Field Based on Rayleigh Model

In order to solve the problem that the relative permeability of the permalloy is missing and difficult to measure accurately in an extremely weak magnetic field (EWMF, <1 nT), a method to measure the permeability in EWMF based on the Rayleigh model is proposed in this paper. In this method, the R...
