In an electromagnetic blood flow meter, the induced voltage is directly proportional to the
In an electromagnetic blood flow meter, the induced voltage is directly proportional to the
Show Hint
EM flow meter output voltage ∝ blood velocity $\propto$ blood flow rate.
Updated On: June 02, 2025
- Blood flow rate
- Square root of the blood flow rate
- Square of the blood flow rate
- Logarithm of the blood flow rate
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
An electromagnetic blood flow meter works on Faraday's law of electromagnetic induction. When blood (a conductive fluid) moves through a magnetic field, it induces a voltage proportional to the velocity of blood flow, hence the flow rate.
