ctromagnetic Induction HOOSE 2 QUESTIONS: a) A flow meter can be used to measure the speed of blood in situations when a blood essel is sufficiently exposed.Blood is conductive enough that it can be treated as a moving conductor. When it flows perpendicularly with respect to a magnetic field, electrodes can be used to measure a small voltage across the vessel. Suppose the speed of the blood is 0.30 m/s and the diameter of the vessel is 5.6mm. In a 0.60 T magnetic field what is the magnitude of the voltage that is measured with the electrodes? b). In some medical procedures, there are safety concerns with an electric current within he body. Suppose the largest surface of the body through which flux passes has an area of 032 m*2 and a normal that is parallel to a magnetic field of 1.5 T. Determine the smallest me period during which the field can be allowed to vanish if the magnitude of the average duced emf is to be kept less than 0.010 V A 0.60-T magnetic field is directed perpendicular to the plane of a circular loop of radius 6 m. What is the magnitude of the magnetic flux through the loop? In the most common form of lightning, electrical charges flow between the ground and a d. The flow changes dramatically over short periods of time. Even without directly ing an electrical appliance in your house, a bolt of lightning that strikes nearby can uce a current in the circuits of teh appliance. Note that such circuits typically contain or loops of wire. Why can the lightning -cause the gurrent to 2.8
