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?
Using an electromagnetic flowmeter, we apply a magnetic field of 0.25 T to coronary artery where the velocity of the blood is 15 cm/s. 1. Positive and negative jons flow to the right in the field of the magnets. 2. An end view shows that the magnetic force on the positive ions is to the right, and that on the negative ions is to the left. v out B of page fra 7. S S 3. The resulting charge separation leads to a potential difference that can be measured between iwo electrodes. Answer the following questions:
