I know that magnetic force on a dipole is dependent on the gradient of the field, but it has not registered completely with me yet. So I created a simple model of a single two inch long, 0.5 inch diameter, N40 neodymium magnet. This represents the simplest magnets that I have. From here, I simulated the field from the surface at the center of the flat surface moving outward (in the same direction as the magnetization). Then I for the lateral force in a flow cell. | |||
