We show that the magnetic field strength profiles closely follow the cluster density profiles outside a core region of radius $\\sim200\\kpc$. The magnetic field has a correlation length of order $50\\kpc$ and reverses on scales of $\\sim100\\kpc$ along typical lines-of-sight. The power spectrum of the magnetic field can well be approximated by a steep power law with an exponent of $\\sim-2.7$.
