Question

When I worked the problem I used e=VBL and found e to be 1.1368 x10^-3 and that was wrong. What do I need to do now? The drawing shows a type of flow meter that can be used to measurethe speed of blood in situations when a blood vessel issufficiently exposed (e.g., during surgery). Blood is conductiveenough that it can be treated as a moving conductor. When it flowsperpendicularly with respect to a magnetic field, as in thedrawing, electrodes can be used to measure the small voltage thatdevelops across the vessel. Suppose the speed of the blood is0.35 m/s and the diameter of the vessel is5.6 mm. In a 0.58-T magnetic field what isthe magnitude of the voltage that is measured with the electrodesin the drawing? 1

Explanation / Answer

       Given that the magnitudeof magnetic field is B = 0.58 T        velocity of blood is v= 0.35 m/s        separation between theelectrodes is L = 5.6mm = 0.0056m -------------------------------------------------------------------------------- The motional emf is = BLv                                 = 1.1368*10-3V                                 = 1.1368 mV
