Magnetic Needle Modeling
I'm hoping to create a model of either a needle or a wire today that will show what will occur if I place a magnetized piece of metal into a flow cell, or tube of ferritin solution. Hopefully next week I will be able to put a magnetized needle or wire into flow cell and see if I can attract ferritin to it. If I can, this might be a complete step up from mounting a gigantic magnetic yoke onto the microscope stage, and will give me finer control over the ferritin. I also want to see if anyone has any neodymium magnets that are in this size range.

Useful links or notes for today:
 * needle dimensions and types
 * syringe needles
 * small cylinder magnets from K&J
 * Ferrite's average maximum strength: 0.35 T
 * very useful data from Wikipedia:

Here is the link for the page I took this from. I managed to create the models, and I will analyze them on Monday.
