Answer:

According to right-hand thumb rule, i] The direction of magnetic field at a point above the power line is form South to North.

Answer:

Given a long horizontal power line carries a current of 100 A in the east-west direction. What is the direction of magnetic field at a point 1.0 m below it

  • So we have a power line. The direction will be in the east west direction.
  • So we have the current I = 100 Amperes. Somewhere there is a point B the value of magnetic field distance is 1.5 m.
  • Now the magnetic field at a point due to long current carrying conductor.
  • So B = μoi / 2πr
  •         = 4π x 10^-7 x 100 / 2 x π x 1.5
  •          = 1.3 x 10^-5 T
  • Now we need to find the direction at this particular point.
  • The direction of the current is flowing from east to west.
  • By using right hand thumb rule we have the magnetic field direction is perpendicular the paper outwards and so it will be towards south direction
