Abstract

We present an experimental model where magnetic balls in a box are used to simulate aggregation of small ferromagnetic particles a few nm in diameter. The aggregation can be characterized by a fractal dimension that increases as the magnetic moment of the particles decreases. The magnetization of the system of balls has been measured in an external magnetic field and compared for different values of the magnetic moments.
