Here are the essential concepts you must grasp in order to answer the question correctly.
Magnetic Field
The magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. It is represented by the symbol B and is measured in teslas (T). The direction of the magnetic field is defined as the direction a north pole of a magnet would move, and its strength can vary depending on the source and distance from it.

Vector Representation
A vector is a quantity that has both magnitude and direction. In physics, vectors are used to represent quantities such as force, velocity, and magnetic fields. When expressing the magnetic field as a vector, it is essential to specify both its strength (magnitude) and its direction, often using coordinate systems or unit vectors to convey this information clearly.

Biot-Savart Law
The Biot-Savart Law describes how electric currents produce magnetic fields. It states that the magnetic field dB at a point in space due to a small segment of current-carrying wire is directly proportional to the current and inversely proportional to the square of the distance from the wire segment to the point. This law is fundamental for calculating the magnetic field generated by complex current configurations.
