Mathematical descriptions of the electromagnetic field - Wikipedia...

There are various mathematical descriptions of the electromagnetic field that are used in the study of electromagnetism, one of the four fundamental forces of nature. In this article three approaches are discussed, generally the equations are in terms of electric and magnetic fields, potentials...

Magnetic fields of currents

The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire.

Electromagnetic Waves

Electromagnetic Wave Equation.

Maxwell's Equations | A Sheet of Current: A Simple Magnetic Field

Maxwell's four equations describe the electric and magnetic fields arising from distributions of electric charges and currents, and how those fields change in time.

Maxwell’s Electromagnetic Field Equation No. 1

Maxwell’s Electromagnetic Field Equation No. 1. By George J. Spix. 1.0 Statement of Equation. The following Electrostatic Field equations will be developed in this section


The objectives of this experiment are: (1) to study and verify the equations for the magnetic field of a pair of Helmholtz coils, (2) to learn about the rationale for using Helmholtz coils, (3)...

The displacement current and maxwells equations

35.2. Maxwells Equations. The fundamental equations describing the behavior of electric and magnetic fields are known as the Maxwell equations.


Solution. (a) From Equation 29-1b, B = F=ev sin θ, which is a minimum when sin θ = 1 (the magnetic field perpendicular to the velocity).
