**6. The electrical efficiency in inductive heating processes who magnetodielectric field concentrators use**

The primary endpoint of this chapter is evidence increased electrical energy conversion efficiency, in the inductor-piece ensemble, that use a magnetodielectric material field concentrator of the type obtained as explained above.

Efficiency for this case, determined from data modeled is:

```
η i could reg = 96% 
η i hot reg = 69%
```

measured line voltage was 378V.

Based on the results of modeling and simulation was made an inductor with magnetodielectric material concentrator. The image of this inductor during the heating

Current drawn from the supply of inductive heating during the process was 60A, and the

For the heating inductive process, without magnetodielectric field concentrator calculated is:

```
η i could reg = 81% 
η i hot reg = 54%,
```
There is a significant increase of 15% for hot and cold regime of electrical energy conversion efficiency, the inductor-piece ensemble.

These values increase efficiency reveal clearly the advantage of using electromagnetic processing systems for heating that are made up of field concentrators made by magnetodielectric materials
