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}}}

Answer:

<h2>Magnetic field required for the given induced EMF is 1.41 T</h2>

Explanation:

Potential difference across the blood vessel is given as

E = vBd

here we know that the speed is given as

v = 14.8 cm/s

d = 4.80 mm

E = 1 mV

now we have

1 \times 10^{-3} = (14.8 \times 10^{-2})B(4.80 \times 10^{-3})

B = 1.41 T

Now volume flow rate of the blood is given as

Q = Av

Q = \frac{\pi d^2v}{4}

from above equation we have

v = \frac{E}{Bd}

Now we have

Q = \frac{\pi d^2\frac{E}{Bd}}{4}

Q = \frac{\pi E d}{4B}

A charged particle is moving perpendicular to a magnetic field in a circle with a radius r. An identical charge particle enters
emmasim [6.3K]

Answer:

<em>The second particle will move through the field with a radius greater that the radius of the first particle</em>

Explanation:

For a charged particle, the force on the particle is given as

F = \frac{mv^{2} }{r}

also recall that work is force times the distance traveled

work = F x d

so, the work on the particle = F x d,

where the distance traveled by the particle in one revolution = 2\pi r

Work on a particle = 2πrF = 2\pi mv^{2}

This work is proportional to the energy of the particle.

And the work is also proportional to the radius of travel of the particles.

Since the second particle has a bigger speed v, when compared to the speed of the first particle, then, the the second particle has more energy, and thus will move through the field with a radius greater that the radius of the first particle.
