The distance from the conductor is inversely proportional to the magnetic field strength. As the distance from the current-carrying conductor increases, the magnetic field strength decreases. This is evident from the diminishing deflection of the compass needle at greater distances from the wire.
What role does the distance from the conductor play in influencing the magnetic field strength?

The strength of the magnetic field around a current-carrying conductor is influenced by the distance from the conductor. According to the right-hand rule, which describes the direction of the magnetic field around a current-carrying wire, the magnetic field strength decreases as you move away from the conductor.
The magnetic field strength (B) at a given point is inversely proportional to the distance (r) from the conductor. Mathematically, this relationship is described by the formula:
B ∝ 1/r

The strength of the magnetic field produced by a current-carrying conductor decreases as you move farther away from the conductor. The relationship between the magnetic field strength (B) and the distance from the conductor (r) is described by the inverse square law, which states that the strength of a field is inversely proportional to the square of the distance from the source.
Mathematically, the inverse square law for magnetic fields can be expressed as:
B∝ 1/r2
This means that as you move away from a current-carrying conductor, the magnetic field strength diminishes rapidly. The magnetic field lines form concentric circles around the conductor, and their strength decreases as the distance squared.
In practical terms, this implies that the influence of a current-carrying conductor on nearby objects, such as a compass needle, is more pronounced when the objects are close to the conductor and becomes weaker as the distance increases. Understanding this relationship is important in applications such as electromagnetics and power transmission, where the behavior of magnetic fields over distance plays a crucial role.
