Module: FQ

Overview

Overview

The purpose of this Application Note is to help JMAG users understand the steps and settings used in a JMAG analysis. It is intended to help those who are working with a new analysis target better understand the analysis steps and the setting contents.
The actual JMAG model described in this Application Note is available for download from the JMAG Application Catalog. This model will allow you to view the model, settings and results. You can also create a template from the model to use as a starting point when analyzing your own geometry. They can be downloaded using the same method as the analysis model data. Please refer to the JMAG manual for more information on templates.

Magnetic Flux Density Distribution

Fig. 1. Lorentz force density distribution

The magnetic flux density distribution generated in the yokes and the air region is shown in fig. 1. The figure shows that Lorentz force is generated toward the inside of the molten metal.
This enables confirmation of the size and direction of the agitation force.

Current Density Distribution

Fig. 2. Current density distribution

The current density distribution generated in the molten metal is shown in fig. 2. You can check the depth and size of the eddy current generated inside the molten metal. The Lorentz force distribution generated in the molten metal is shown in fig. 2.

Magnetic Flux Density Distribution

Fig. 3. Magnetic flux density distribution

The magnetic flux density distribution generated in the molten metal is shown in fig. 3.

Lorentz Force of Molten Metal

Table 1. Magnetic flux density distribution

The Lorentz force of the molten metal is shown in Table 1. We learned the force of the axis direction component Z is small and radial direction component R is large.
