Learn how to determine the cause of electromagnetic coupling by understanding how it is coupled from source to receiver.
1 Henry is defined as the amount of inductance required to produce an emf of 1 volt in a conductor when the current change in the conductor is at the rate of 1 Ampere per second.An electric current flowing through a conductor creates a magnetic field around it. The strength of the field...
grounding conductor and cable presents low impedance, it is easy to spread when the current is injected into these conductors. When the noise is transmitted to other sensitive circuits, it can cause interference. At high frequency, the inductance and capacitance of the conductor will not be ignore...
Where L is the inductance in Henrys, µ is the permeability constant, i.e. a coefficient of how easily the magnetic field can be created in a given medium, n is the number of turns, a is the area of the coil and l is the length of the coil. Again, the Henry is a very large...
This transmission circuit may include wires, conductive members of the device, power supplies, common impedances, ground planes, resistors, inductors, capacitors, and mutual inductance elements, among others. Radiation transmission is propagating through the medium in the form of electromagnetic waves, ...
The working principle of an electromagnet is: Individual magnetic fields cancel each other out when the atoms in the nail are orientated in arbitrary ways. Under the influence of electric current, these atoms are reoriented to point in the same direction. ...
The SI unit of inductance is Henry abbreviated as 'H'. Here students will find a detailed explanation about the inductance units (SI Unit and Other Inductance Units). Visit to know more.
Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate. More commonly, though, when we speak of electric current, we mean the more controlled ...

Chapter One – What is an Electric Coil? An electric coil, or electromagnetic coil, consists of a series of conductive wires wrapped around a ferromagnetic core, which can be cylindrical, toroidal, or disk-shaped. As one of the simplest electronic components, electric coils provide inductance in...
