✦ Synopsis

In this paper, numerical integral methods are proposed to simulate fluxgate behaviour. The goal of this work is to improve fluxgate magnetization description with efficient numerical methods and to favourably replace the classical, and still used a lot, demagnetization factor. To begin with, the numerical integral methods are briefly stated and their advantages and drawbacks are discussed. Then, they are evaluated on a well known and widely studied fluxgate which is the ring-core. The results appear to be close to the experimental data. In addition, these methods corroborate some assumptions made in previous papers by different authors.

We present a new simulation code for electrostatic waves in one dimension which uses the Vlasov equation to integrate the distribution function and Ampère's equation to integrate the electric field forward in time. Previous Vlasov codes used the Vlasov and Poisson equations. Using Ampère's equation
