The deflection of a compass needle near a current-carrying wire is governed by the right-hand rule. According to this rule, if you grasp the wire with your right hand, with your thumb pointing in the direction of the current, and your fingers encircling the wire, the magnetic field lines around the wire will follow the direction of your fingers.
If you increase the current flowing through the wire, the magnetic field produced around the wire becomes stronger. This, in turn, affects the deflection of the compass needle. The compass needle aligns itself with the magnetic field lines, so an increase in current results in a stronger magnetic field, leading to a greater deflection of the compass needle.
In summary, increasing the current in the copper wire increases the strength of the magnetic field around the wire, leading to a larger deflection of the compass needle.

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.

The magnetic field around a current-carrying straight wire follows a specific pattern that changes with distance. As you move away from the wire, the magnetic field strength decreases. The behavior can be summarized as follows:
1. Close to the Wire: Near the current-carrying wire, the magnetic field is stronger. The magnetic field lines form concentric circles around the wire, and the field strength is relatively higher in this close vicinity.
2. Increasing Distance: As you move farther away from the wire, the strength of the magnetic field diminishes. The concentric circles representing the magnetic field become larger with increasing distance.
3. Inverse Square Law: The relationship between the magnetic field strength (B) and the distance (r) from a long, straight current-carrying wire follows an inverse square law. Mathematically, this relationship is expressed as B ∝ 1/r^2, where B is the magnetic field strength, and r is the distance from the wire.
4. Weakening Effect: The magnetic field strength decreases rapidly with distance. This weakening effect is a characteristic feature of the magnetic field produced by a current flowing through a straight conductor.
In summary, the magnetic field around a current-carrying straight wire weakens with increasing distance from the wire, following the principles of the inverse square law. This understanding is crucial in various applications, such as designing circuits and electromagnetic devices, where the interaction between current and magnetic fields plays a significant role.

If the compass is moved away from the copper wire while keeping the current constant, the deflection of the needle decreases. The deflection of the compass needle is directly related to the strength of the magnetic field produced by the current in the wire.
As the distance between the compass and the current-carrying copper wire increases, the magnetic field experienced by the compass becomes weaker. The relationship between the magnetic field strength (B), current (I), and the distance from the wire (r) follows an inverse square law, expressed as B ∝ 1/r². Therefore, as the distance increases, the magnetic field strength decreases, resulting in a reduced deflection of the compass needle.
In summary, maintaining a constant current but moving the compass away from the copper wire leads to a decrease in the deflection of the needle due to the diminishing strength of the magnetic field with increasing distance.

The change in deflection of the needle in response to a change in current reveals a direct relationship between the current in the conductor and the strength of the magnetic field produced. Specifically:
1.Increase in Current: If the current in the conductor is increased, the deflection of the compass needle also increases. This indicates that an increase in current results in a stronger magnetic field around the current-carrying conductor.
2. Decrease in Current: Conversely, if the current in the conductor is decreased, the deflection of the compass needle decreases. A decrease in current leads to a weaker magnetic field.
In summary, the deflection of the needle is a qualitative indicator of the strength of the magnetic field. The key takeaway is that the magnitude of the magnetic field produced at a given point increases with an increase in the current through the wire. This relationship is fundamental to the principles of electromagnetism and is crucial in various applications in physics and electrical engineering.
