Open navigation menuMaxwell formulated a set of equations involving electric and magnetic fields, and their sources, the charge and current densities. These equations are known as Maxwell’s equations. Together with the Lorentz force formula (Chapter 4), they mathematically express all the basic laws of electromagnetism.This third of Maxwell's equations, Equation 16.10, is Faraday's law of induction and includes Lenz's law. The electric field from a changing magnetic field has field lines that form closed loops, without any beginning or end. 4. Ampère-Maxwell law. Magnetic fields are generated by moving charges or by changing electric fields.Oliver Heaviside FRS (/ ˈ h ɛ v i s aɪ d /; 18 May 1850 – 3 February 1925) was an English self-taught mathematician and physicist who invented a new technique for solving differential equations (equivalent to the Laplace transform), independently developed vector calculus, and rewrote Maxwell's equations in the form commonly used today.
