Magnet failures with circulating beam in the LHC can lead to losses that could produce damage within times as short as 3 ms. In order to characterize the distribution and evolution of these losses, tracking simulations with variable magnetic field have been done using MADX. The effects on the beam of dipole and quadrupole failures have been characterized and are presented for the most critical LHC magnets and circuits. The transverse distribution of primary losses in the collimators have been studied and loss patters of secondary losses for primary impacts at different locations have been evaluated. Based on these studies, the redundancy of the LHC Machine Protection Systems in case of magnet failures with circulating beam is evaluated.
