How is the reluctance of the interleaved corner related with the magnetizing current?

The reluctance of an interleaved corner in electrical engineering, particularly in the context of transformers and inductors, relates to the magnetizing current through its effect on the magnetic circuit’s efficiency and performance. Reluctance is a measure of the opposition that a material or a section of a material presents to the establishment of a magnetic flux within it, analogous to electrical resistance’s role in opposing electric current.

When interleaved corners are used in the core design of transformers or inductors, they serve to reduce the overall magnetic reluctance of the core. This reduction in reluctance occurs because the interleaving improves the magnetic path, making it easier for the magnetic flux to flow through the core material. Essentially, the better the magnetic flux flows, the lower the reluctance.

A direct relationship exists between the reluctance of the magnetic path and the magnetizing current required to achieve a certain level of magnetic flux in the core. The magnetizing current is the current required to magnetize the core material. A higher reluctance requires a higher magnetizing current to achieve the same level of magnetic flux, whereas a lower reluctance requires a lower magnetizing current for the same flux level.

So, in the case of the interleaved corners reducing the core’s reluctance, they effectively reduce the amount of magnetizing current needed. This has several beneficial effects:
1. Improved Efficiency: Lower magnetizing current means that less energy is wasted as heat, improving the overall efficiency of the device.
2. Reduced Core Losses:
