Blood contains positive and negative ions and therefore is aconductor. A blood vessel, therefore, can be viewed as anelectrical wire. We can even picture the flowing blood as a seriesof parallel conducting slabs whose thickness is the diameterd of the vessel moving with speed{v}A) If the blood vessel is placed in a magnetic field B perpendicular to the vessel, as in the figure, show that the motional potential difference induced across it is{\cal{E}}\: =\:{vBd}.B) If you expect that the blood will be flowing at 14.8 {\rm cm}/{\rm s} for a vessel4.80 {\rm mm} in diameter, what strengthof magnetic field will you need to produce a potential differenceof 1.00 {\rm mV}?C)Show that the volume rate of flow (R) of the blood is equal to {R\:=\:}{{\pi {{\cal{E}}{d}}}\over {{{4}}{B}}}

"1.41 T" would be the required magnetic field.

According to the question,

Speed,

Diameter,

Potential difference,

Potential difference across the blood vessel will be:

→          

By substituting the values, we get

→

→            

Now,

The volume flow rate will be:

→

from the above equation, we get

→

then

→

Thus the above approach is right.

Explanation:

Potential difference across the blood vessel is given as

here we know that the speed is given as

now we have

Now volume flow rate of the blood is given as

from above equation we have

Now we have

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
