What are the colours of live, neutral and earth wires?

A long vertical wire in which a current is flowing produces a neutral point with the earth's magnetic field at a distance of 5 cm from the wire. If the horizontal component of the earth's magnetic induction is 0.18 gauss, then of the wire is

A vertical wire in which current is flowing produces a neutral point with the earth's horizontal field at a distance of 5 cm from the wire in air . What is current , if B_(H) = 0.18 xx 10^(-4) T ?
