Physics

Blood contains positive and negative ions and therefore is aconductor. A blood vessel, therefore, can be viewed as anelectrical wire. We can even picture the flowing blood as a seriesof parallel conducting slabs whose thickness is the diameterd of the vessel moving with speed{v}A) If the blood vessel is placed in a magnetic field B perpendicular to the vessel, as in the figure,show that the motional potential difference induced across it is{\cal{E}}\: =\:{vBd}.B) If you expect that the blood will be flowing at 14.8 {\rm cm}/{\rm s} for a vessel4.80 {\rm mm} in diameter, what strengthof magnetic field will you need to produce a potential differenceof 1.00 {\rm mV}?C)Show that the volume rate of flow (R) of the blood is equal to {R\:=\:}{{\pi {{\cal{E}}{d}}}\over {{{4}}{B}}}
