Maxwell's Equations are a set of four fundamental equations that describe how electric and magnetic fields interact with each other and with charges/currents. They form the foundation for understanding electromagnetic phenomena.
One of Maxwell's Equations that relates electric fields to the distribution of electric charges.
One of Maxwell's Equations that describes how a changing magnetic field induces an electric field.
Ampere-Maxwell Law: One of Maxwell's Equations that relates magnetic fields to currents and changing electric fields.
