How large a current would a very long, straight wire have to carry so that the magnetic field 1.80 cm from the wire is equal to 1.00 g (comparable to the earth's northward-pointing magnetic field)? ii = nothing a request answer part b if the wire is horizontal with the current running from east to west, at what locations would the magnetic field of the wire point in the same direction as the horizontal component of the earth's magnetic field? if the wire is horizontal with the current running from east to west, at what locations would the magnetic field of the wire point in the same direction as the horizontal component of the earth's magnetic field? at all points directly south of the wire at all points directly below the wire at all points directly north of the wire at all points directly above the wire request answer
