Answer:
The magnetic field points northwards
Explanation:
This is because a radial magnetic field is generated round the wire and its direction is always in the direction of the tangent to the circle at distance R from the wire. Due east of the wire, the tangent to the circle at radius, R points northwards. So, the direction of the magnetic field at that point is north.
