We present results for a pulsar magnetosphere model where the rotational and magnetic field axes are not aligned. Interior neutrons are assumed to be uniformly magnetized and suffer spontaneous magnetization. We find the structure and magnitude of the external E and B fields as a function of rotational speed and angle between axes. The structure of the external B field is a dipole if the magnetization and rotation axes are aligned. Otherwise it contains higher poles such as quadrupole, octopole, etc. Higher order terms in the B field affect radiation processes such as curvature radiation and pair production. The external E field has a dipole form unlike the standard model, which predicts a quadrupole. We model this to see how to track the particle trajectories. Our hope is to define the pulsar emission region and then calculate the radiation spectrum from particles moving through the magnetosphere.
