What is the magnetizing inductance?

Magnetizing inductance is associated with the flux that actually links the core of the transformer (as opposed to leakage flux, which does not). If you’re familiar with the ‘open circuit test’ for a transformer that’s used to measure Xm, think about how the test is performed.

How do you calculate magnetizing inductance?

When you measure the primary winding when the secondary is closed just the leakage inductance is measured. To get the magnetizing inductance you need to subtract the open measurement from the closed measurement.

What is magnetizing reactance?

The magnetizing reactance is defined as the result of calculating the electric machine magnetic circuit. In this chapter, the magnetic circuit is calculated by the use of an electric equivalent circuit, the elements of which represent the magnetizing reactance values of magnetic circuit regions.

What is inductors and self inductance?

A circuit element used to provide self-inductance is known as an inductor. The induced emf across an inductor always acts to oppose the change in the current. This can be visualized as an imaginary battery causing current to flow to oppose the change in (a) and reinforce the change in (b).

What is formula of self inductance?

Self-inductance Formula We can derive an expression for the self-inductance of a coil from Faraday’s law of electromagnetic induction. VL = −N (dϕ / dt) Where: VL = induced voltage in volts. N = number of turns in the coil.

What is a magnetic magnetizing inductance?

Magnetizing inductance is really a transformer or induction motor term. The general term is self inductance. Self inductance is the inductance of a coil, affected by the number of turns, core material and core geometry. Two separate coils each have self inductance in accordance with these parameters.

What is the difference between mutual inductance and self inductance?

Magnetizing inductance should refer to self inductance of an inductor with magnetic core while mutual inductance refers to entangled flux between two different coils which share (or not) a core.

What is the self inductance of an electric coil?

When magnetism builds up in the coil, this magnetism induces a voltage in the coil to oppose the applied voltage and limit the current. Self inductance is the inductance that any conductor of electricity has, just because of its length, even if nothing else is near it. Its an inherent property of an electrical conductor.

What is self-inductance of a magnetic core?

If you have a core that is made up of a magnetic material of permeability μ, then The self-induced emf is also called the back emf as it opposes any change in the current in a circuit. Physically, the self-inductance acts as inertia. In mechanics, it is also the electromagnetic analogue of mass.
