Magnetic fields play an important role in almost all astrophysical phenomena, including star formation. Due to the difficulty of analytic modeling and observations, magnetic fields are still poorly studied, and numerical simulation has become a major tool. We have implemented a cosmological magnetohydrodynamics package for Enzo, an AMR hydrodynamics code designed to simulate structure formation. We use the TVD solver developed by S. Li as the base solver. In addition, we employ the constrained transport (CT) algorithm as described by D. Balsara. For interpolating magnetic fields to fine grids we used a divergence free quadratic reconstruction, also described by Balsara. We present results from several test problems including MHD caustics, MHD pancakes, and galaxy cluster formation with magnetic fields. We also discuss possible applications of our AMR MHD code to first star research.
