Component Finder

When you are designing a transformer or inductor, one key issue is to use a suitable core and material. In Magnetic Builder, after selecting a suitable core from component finder, you can press "Core material" to choose the material.

By default, you can see all suggested materials from core manufacturer.

If necessary, you can change the default material list box to "No" and see other materials from that core manufacturer.

Magnetic Builder
Magnetic Builder is a tool that can build customized transformer or inductor. However, not all settings are possible for real world. For example, the winding space may not be enough. In these cases, winding wizard is a very useful tool to solve the problem.

When user's customized setting is not valid, you may see the message "Winding space is not enough. Press OK to view the possible solution suggested by winding wizard." User can click OK to see the winding wizard page.
Winding wizard will suggest a possible solution to solve the winding space not enough problem. If user do not like the suggested solution, user can tune the setting like choosing less number of turn instead of choosing a thinner wire. Then, press "Update" to run the wizard again to see the suggestion after applying new setting.

Finally, user can press "Accept" to use this suggested transformer or press "Deny" to roll back to use the original transformer. The "Do not ask me again by always apply above rules." checkbox can force the system to remember user's setting and apply winding wizard's suggested solution without any more prompt when the user's setting is void again.
