Hey I am having trouble with the following question.
Because blood contains charged ions moving blood develops a Hall voltage across the diameter of an artery. The blood in a large artery with a diameter of 0.85 cm has a flow speed of 0.6 m/s. If a section of this artery is in a magnetic field of 0.4T, what is the potential diference across the diameter of the artery? I have an idea of what is going on in the question, but it seems i havn't been given enough information to solve it. I know that hall voltage is given by: V = (IB)/ned and i know that F = qvB if i assumed the field was perpendicular to the artery I could use that for something  maybe. But really im stumped, any help, or even a formula i have over looked would be great thanks. ~Daniel
