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. | 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.

Various Magnet Set UpsI've put together a couple of simulations to test which one would be the most useful set up to have mounted on the microscope stage so that I can observe the ferritin while it is under the influence of the magnet. After running these simulations, I was able to calculate the average force a single ferritin would feel in four different cases:
Here are the forces that I calculated for the various models: {{#widget:Google Spreadsheet |

}} The ModelsIn addition to the standard yoke, which comes in 0.1" and 0.4" gaps here, I created four other models that best represent the different ideas that I came up with, or represent a simple idea.
