The magnetic field lines around a straight conductor carrying a current are concentric circles. The direction of a magnetic field is given by the Right-Hand Thumb Rule.

Right-Hand Thumb Rule:

Imagine that you are holding a straight current-carrying conductor in your right hand such that the thumb points towards the direction of the current. Then, your curved fingers wrapped around the conductor point in the direction of the field lines of the magnetic field.

The magnitude of the magnetic field due to a straight current-carrying conductor at a given point is

Directly proportional to the current flowing through the conductor.
Inversely proportional to the distance of that point from the conductor.
