Where N is the number of turns and Φ is the amount of flux.
As per Faraday’s law of inductance, the generated EMF is proportional to the rate of change of the magnetic flux. To understand further, understanding of Faraday’s law of inductance is required.
So, as of now, there is a magnetic field across inductors, produced by the current flowing through it. Magnetic Flux also has a unit in SI standard, it is Weber. Now, what is Magnetic Flux? Well, it is the measurement or quantity of the magnetic field which passes through a specified area. This magnetic field is measured in the SI unit, Tesla (T). Therefore, if the current is increased, so the magnetic field will also increase. These two things are linearly proportional. Inductors are used in almost every electronic product, some DIY applications of inductor are:īefore discussing further, it is important to understand the difference between two terminologies, Magnetic Field and Magnetic Flux.ĭuring the Current flow through the conductor, a magnetic field is generated. This additional capacitance, as well as wire resistance, alters the high-frequency behaviors of an inductor. The closely wrapped coils produce a measurable amount of stray capacitance between coil turns. Real inductor not only has inductance, but it also has capacitance and resistance. There is a huge difference between Ideal Inductor and the actual real inductors used in electronic circuitry. The inductance of an Inductor is highly dependable on multiple factors, such as number of turns of wire, the spacing between the turns, no of layers of turns, type of core materials, its magnetic permeability, size, shape etc. The coil can be different in shapes & sizes and also can be wrapped in a different type of materials. Inductors are formed using insulated copper wires which further formed as a coil. The symbol is a representation of twisted wires which means wires are constructed to become a coil. The symbol of an inductor is shown in the below image. Typically, much lower values like, Milli Henry, Micro Henry or Nano Henry are used in most of the applications. In Electronics the inductor with a value of Henry is rarely used as it is a very high value in terms of the application. If the current flow through an inductor is changed at the rate of one ampere per second and 1V of EMF is produced inside the coil, then the value of inductance will be 1 Henry. The inductor is characterized by the value of inductance which is the ratio of voltage (EMF) and current change inside the coil.
