The hall voltage will be calculated using the formula:

E = Blv

where:

>Hall voltage: E = ?

>Magnetic field:

B = 0.200 Tesla or Wb/m^2

>Width of conductor or Diameter of Aorta:

l = 2.60 cm, converting to meter =.0260 m

>Velocity of charge flowing:

v = 60 cm/s, converting to meter = 0.6 m/s

Substituting the given:

E = (0.200 Wb/m^2) * (0.260 m) * (0.6 m/s)

E = (0.200 Wb/m^2) * (0.156 m^2/s)

E = 0.0312 Wb/s

Since 1 volt = 1 Wb/s then,

E = 0.0312 V or 31.2 mV
