When it flows field, perpendicular electrodes can to a be magnetic used to field, measure electrodes the small can voltage be used that to develops measure across the the vessel. small voltage Suppose that the develops speed of across the blood the is 0.3 m/s, the diameter of the vessel is 5.6 vessel. mm and B = 0.6 T. What is the magnitude of the voltage that is measured? Provide detailed explanation.

Problem 7 The drawing shows a type of blood flow meter. Blood is conductive enough that it can be treated as a moving conductor. When it flows perpendicular to a magnetic field, electrodes can be used to measure the small voltage that develops across the vessel. Suppose the speed of the blood is 0.3 m/s, the diameter of the vessel is 5.6 mm and B = 0.6 T. What is the magnitude of the voltage that is measured? Provide detailed explanation X Electrode B X + + + Blood > L TG X L = 5.6 mm Blood - a moving conductor X Electrode
