A moving electron makes a magnetic field so moving matter that is full of electrons should make a magnetic field. Magnetars are a cosmic example but has a magnetic field ever been measured from a moving object on earth. An experiment that springs to mind is the 200lb gyroscope that Professor Laithwaite, the inventor of the linear motor did, where he couldn't lift it but once it was set spinning he could raise it above his head with one hand. Could this be that the spinning gyroscope generates a magnetic field like a magnetar and alters gravity. Laithwaite always believed there was something going on with the gyroscope but was ridiculed by the narrow minded establishment like all geniuses.
