Steady Currentn of current holds generally based on the principle of conservation of charge. We need to apply an electric potential difference, i.e., a voltage, to a material to transport a current through it. It is well known that Ohm’s law holds empirically, which assumes a proportional relationship between the

Current and Magnetic Flux Densitye that is produced by the currents. This distortion is the magnetic field and is represented by the magnetic flux density. The magnetic flux density produced by current is described by the Biot-Savart law. On the other hand, Ampere’s law describes the global relationship between the current and the

Electromagnetic Inductionme. The electromotive force appears to induce a current in a closed circuit in such a way as to reduce any change in the magnetic flux penetrating it. This is Faraday’s law. As a result, the electric field is no longer irrotational and has a vortex caused by a variation in the magnetic flux density

Electromagnetic Wavespeed. It is shown that the electric field and the magnetic flux density are perpendicular to each other and are perpendicular to the propagation direction. We discuss the refraction and reflection of a plane electromagnetic wave on an interface between two substances with different material constan
