Godunov methods have proved in recent years to be very efficient numerical schemes to solve the hydrodynamic equations. Here, we present an extension of the 3D adaptative Mesh Refinament (AMR) code RAMSES (Teyssier 2002) to the equations of magnetohydrodynamics (MHD). The code uses the constrained transport scheme, which garantees that the divergence of the magnetic field is kept to zero to machine accuracy at all time. Different MHD Riemann solvers can be used, and the use of the MUSCL-Hancok approach combines a good accuracy with a fast exectution of the code. A variety of tests will illustrate the performances of the code and the possibilities offered by the AMR scheme. Future applications of the code are discussed.
