    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
