Question

The artery has an inner diameter of 2.85 mm and passes through a region where the magnetic field in 0.065 T. i) If the voltage difference between the electrodes is 210 microV, what is the speed of the blood? ii) Which electrode is at the higher potential? Does your answer depend on the sign of the charged particles in the blood?

Does your answer depend on the sign of the charged particles in the blood?

Explanation / Answer

The artery has an inside diameter of 2.35 mm and passes through a region where the magneticfield is 0.065 T.? a) If the voltage difference between the electrodes is 210 µV, what is the speed of the blood? 1 m/s v = V/(wB), where V is Hall voltage, w is width or diameter and b is magnetic field. v = 1.375 m/s.
