Could someone give me a word definition of Ampere's Law as I have googled some definitions and they all seem a bit confusing. Thanks :)

Zz.
Ampere's Law is a fundamental principle in electromagnetism that relates the magnetic field created by a current-carrying wire to the electric current passing through it.
Ampere's Law is expressed as ∮B·dl = μ0I, where ∮B·dl represents the integral of the magnetic field around a closed path, μ0 is the permeability of free space, and I is the electric current enclosed by the path.
Ampere's Law allows us to calculate the magnetic field created by a current-carrying wire, which is essential in understanding the behavior of electromagnets and other devices that use magnetic fields.
Ampere's Law is used in various technologies, such as electric motors, generators, and transformers. It is also important in the design of magnetic resonance imaging (MRI) machines and particle accelerators.
Ampere's Law is only applicable to steady currents and does not account for the effects of changing electric fields. It also assumes that the magnetic field is constant and does not take into account any variations in the magnetic field over time or space.
