Question

Because blood contains charged ions, moving blood develops a Hall voltage across the diameter of an artery. A large artery with a diameter of 0.75 cm has a flow speed of 0.9 m/s. If a section of this artery is in a magnetic field of 0.24 T, what is the maximum possible potential difference across the diameter of the artery? Answer in units of mV.

Answer 1

Answer:

maximum possible potential difference = 1.62 mV

Explanation:

given data

diameter d = 0.75 cm = 0.75 × $10^{-2}$ m

flow speed v = 0.9 m/s

magnetic field B = 0.24 T

to find out

maximum possible potential difference across the diameter

solution

we know that maximum possible potential difference formula is

Vh = Vd× B × d    .............................1

put here value in equation 1 we get

maximum possible potential difference = 0.9 × 0.24 ×  0.75 × $10^{-2}$

solve we get

maximum possible potential difference = 1.62 × $10^{-3}$

maximum possible potential difference = 1.62 mV
