A set of equations that involve the electric and magnetic fields, and their sources, charge and current density, are known as the equations of ______.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Maxwell.
A set of equations involving electric and magnetic fields, along with their sources, charge, and current density, are known as the equations of electromagnetism. These equations are fundamental to understanding the behavior of electromagnetic waves and their interaction with matter. They are commonly referred to as Maxwell's equations, named after the physicist James Clerk Maxwell, who formulated them in the 19th century. Maxwell's equations describe how electric and magnetic fields are generated, propagate, and interact, forming the basis of classical electromagnetism.
