The current i that flows through an inductor produces a magnetic flux that is proportional to it. Circuit an inductor produces inductive reactance which causes the current to lag the voltage by 90 degrees.

Mutual inductance is an inductive effect where a change in current in one circuit causes a change in voltage across a second circuit as a result of a magnetic field that links both circuits.
Effect of inductor on current. And i would like one more question what is the effect of load resistance has on inductor current on dc dc converter. According to lenzs law the induced voltage has a polarity direction which opposes the change in current that created it. This phase angle of reactive opposition to current becomes critically important in circuit analysis especially for complex ac circuits where reactance and resistance.
Stack exchange network stack exchange network consists of 175 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers. Because the inductor reacts to a changing current it is known as a reactive component. Is called inductive reactance x l.
This effect is used in transformers. The opposition that an inductor presents to ac. If the hysteresis of the core material is significant this will also have strange effects on the inductance of the coil.
Effect of frequency on inductive reactance. For this effect to be noticed. The ability of inductors to store energy means that when a current is applied to the inductor it will start to store that energy instead of passing it through to the system.
When the current flowing through an inductor changes the time varying magnetic field induces an electromotive force emf voltage in the conductor described by faradays law of induction. But unlike a capacitor which oppose a change of voltage across their plates an inductor opposes the rate of change of current flowing through it due to the build up of self induced energy within its magnetic field. Inductor designers try to minimize these effects by designing the core in such a way that its flux density never approaches saturation levels and so the inductor operates in a more linear portion of the bh curve.
Mathematically we say that the phase angle of an inductors opposition to current is 900 meaning that an inductors opposition to current is a positive imaginary quantity. This can be used to. When indicating an inductor on a circuit diagram or within an equation generally the symbol l is used.
When you put a light bulb in series with a inductor the inductive reactance of the inductor reduces the current available to the light bulb making it less bright.
