A surveyor is using a magnetic compass 4.8 m below a power line in which there is a steady current of 76 A. (a) What is the magnetic field in microteslas at the site of the compass due to the power line? (b) Will this field interfere seriously with the compass reading? The horizontal component of Earth's magnetic field at the site is 20 μT.
