I can't seem to understand why a current outside of a loop doesn't contribute in Ampere's Law? Any clarification would be appreciated.
Ampere's Law is a fundamental law in electromagnetism, which states that the magnetic field created by an electric current is proportional to the electric current and the distance from the current.
Ampere's Law is used in many practical applications, such as motors, generators, and transformers. It is also used to calculate the magnetic fields of wires and solenoids.
The mathematical formula for Ampere's Law is B = μ₀I/2πr, where B is the magnetic field, μ₀ is the permeability of free space, I is the electric current, and r is the distance from the current.
Ampere's Law and Gauss's Law are both fundamental laws in electromagnetism. While Ampere's Law deals with the relationship between electric currents and magnetic fields, Gauss's Law deals with the relationship between electric charges and electric fields.
Yes, Ampere's Law can be used to calculate the magnetic field of any current-carrying wire as long as the wire is straight and the current is constant. For more complex situations, such as a wire with varying current, other methods such as Biot-Savart Law may be used.
