Question

The magnitude of magnetic field produced by an
infinitely long current carrying conductor at a
perpendicular distance R from the conductor is
μοί
given by B = 27R and its direction is given by right
hand thumb rule, where
Ho = Permeability of vacuum (a constant) = 4 T *
10-7 Tm/A
B = Magnetic field strength (in tesla)
i = Current flowing in conductor (in ampere)
R Distance from conductor (in meter)
Then consider a current 10A is flowing in a
straight conductor of infinite length. At what
distance in meters from the wire the magnetic
field will be 5 x 10-71?​
