Then, what is magnetizing reactance?

The magnetizing reactance is defined as the result of calculating the electric machine magnetic circuit.

One may also ask, what is magnetizing inductance in transformer? 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.

In this manner, what is Magnetising reactance of transformer?

In circuit theory terms, the magnetising reactance is simply the reactance due to the self-inductance of the primary of the transformer. In most transformers the reluctance of the core is small, and as a result the magnetising current (Im) is much smaller than the normal full-load (rated) primary current.

What is XM in transformer?

In a transformer model, Xm is simply the inductance of the primary winding and the core. Introducing a ferromagnetic core changes this behavior by dramatically increasing primary inductance at lower primary voltages (i.e., during normal operation).
