Abstract
The present teachings provide for a method of balancing a shaft. The method can include depositing a mixture of a liquid and ferromagnetic particles on a first surface of a shaft. The first surface can be disposed about a longitudinal axis of the shaft. The method can include rotating the shaft about the longitudinal axis at a first angular velocity. The method can include applying a first magnetic field distribution to the rotating shaft to move the ferromagnetic particles into a desired weight distribution about the first surface. The method can include solidifying the liquid to fix the ferromagnetic particles to the first surface in the desired weight distribution.
