System and methods for monitoring electric machines are provided. A magnetic field associated with the electric machine is measured at one or more points external to the electric machine, wherein a respective magnetic field value is associated with each of the one or more points. The one or more measured magnetic field values are compared to one or more corresponding expected values, and a determination of whether a fault is present in the electric machine is made based at least in part on the comparison.
