Chapter 19: Ampere’s Law
19.1 Introduction In this chapter, we will introduce Ampere’s law, which relates the magnetic field around a closed loop to the total electric current passing through the loop. Ampere’s law is an essential tool for calculating the magnetic fields generated by steady currents in wires and other conductive materials. 19.2 Ampere’s Law Ampere’s law states…

Maxwell’s Equations
Introduction Maxwell’s equations are a set of four differential equations that form the foundation of classical electrodynamics, classical optics, and electric circuits. These four equations describe how electric and magnetic fields interact. They were derived by James Clerk Maxwell in the 19th century. The Four Equations where is the divergence of the electric field ,…

Magnetism
Introduction Magnetism is a physical phenomenon produced by moving electric charge that results in attractive and repulsive forces between objects. It is one aspect of the combined electromagnetic force and shares many similarities with electricity, which is why they are usually thought of together as electromagnetism. Magnetic Fields and Magnetic Force Magnetic fields are a…

Magnetic Field
Introduction A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength), so it is a vector field. Magnetic Force on a Moving Charge The force exerted…

Ampere’s Law
Introduction Ampere’s Law, named after its founder André-Marie Ampère, is a fundamental law in electromagnetism that relates magnetic fields to the electric currents that generate them. It is one of Maxwell’s four equations, which together form the basis of classical electrodynamics. Ampere’s Law in Integral Form Ampere’s law can be stated in its integral form…
