Most basic laws in electromagnetic theory were established in the 19th century by a variety of talented scientists, including Oersted, Ampère, and Faraday. Later, James Clerk Maxwell unified these basic laws into fundamental equations, which macroscopically state the relations between electromagnetic fields and their sources (current and charge). These fundamental equations are called Maxwell’s equations. Let us first consider Maxwell’s equations in a differential equation form.
