Assigning a Coil for a 2D Eddy Current Solver

To assign a coil as an Eddy current excitation:

1. Select the section of the geometry on which you want to apply the excitation (typically a 2D object).
2. Click Maxwell 2D > Excitations > Assign > Coil. (You can also right-click an existing winding in the project tree, and select Assign Coil.)

The Coil Excitation dialog box appears.

3. On the General tab, enter a name for the excitation in the Name box, or accept the default.
4. In the Parameters section, enter the number of conductors for the coil in the Number of Conductors box.
5. Select one of the following for the Polarity:
• Positive
• Negative
• Function
6. If you selected Function as the Polarity, enter a function in the text box.
7. Optionally, on the Defaults tab, click Save Defaults to save the current settings or click Revert to Standard Defaults to revert to the default values in the dialog box.
8. Click OK to assign the coil to the selected object.

To add this coil to an existing winding:

1. In the Project Manager tree, right-click the coil terminal, and select Add to Winding. The Add to Winding dialog box appears.
2. Select the winding to which you ant to add the coil terminal, and click OK.

To remove a coil terminal from an existing winding:

• In the Project Manager tree, right-click the coil terminal, and select Remove from Winding. The terminal is removed from the winding and moved up one level in the project tree (directly beneath Excitations).
• Alternatively, all coils assigned to a winding may be deleted by right-clicking the winding in the project tree and selecting Delete All Coils.
