An electromagnetic flowmeter is used to meausre blood flow rates during surgery. Blood containing Na+ ions flows due south through an artery with a diamter of 0.40 cm. The artery is in a downward magnetic field of 0.25 T and develops a Hall voltage of 0.35 mV across its diameter.

a.) What is the bloos speed in m/s?

b.) What is the flow rate in m^3/s? c.) The leads of a voltmeter are attached to diametrically opposed points on the artery to measure the Hall voltage. Which of the two leads is at the higher potential?
