University of Virginia Electrical Field and Electromagnetic Flowmeter Questions

 

Using an electromagnetic flowmeter, we apply a magnetic field of 0.25 T to a coronary artery where the velocity of the blood is 15 cm/s.

Answer the following questions:

– What force is felt by an Na+ ion?

– What is the strength of electric field produced by the blood as it separates to balance the magnetic force?

– If the artery has a diameter of 3.0 mm, what voltage does this electric field produce?
