Magnetic field is a vector. The diagram or sketch of a magnetic field will show how a magnetic force is acting in that area. A uniform magnetic field is presented by parallel & equidistant straight lines all pointing in the same direction. ... Hence field is the force acting around a particular area of a body.

a)Simply stated, the Right Hand Rule says that the magnetic field lines produced by a current-carrying wire will be oriented in the same direction as the curled fingers of a person's right hand (in the “hitchhiking” position), with the thumb pointing in the direction of the current flow.
b)the direction will be East to West because it is straight conductor
6)Answer
The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections below. One useful analogy is the close connection between magnetic monopoles and electric charges.We adopt a few conventions about field lines:
Since we agree to define the locii in terms of the motion of the north monopole, the field lines enter the south pole and emerge out of the north pole of magnetic dipoles.
In principle, the field lines can be calculated at every position in space, but this is hard to represent in a visual medium, therefore we use the density of field lines to indicate the field strength.
