Will grinding of high frequency transformer core affect pi?

Whether the influence circle will be tested after grinding of high-frequency transformer core depends on the grinding position, which will affect the grinding of the cross-sectional area of magnetic flux path, but whether the influence circle can be measured depends on the change of air gap size before and after grinding. If the change is very small, it will generally have no impact, and naturally it will not be measured. If there is a big change, it goes without saying. However, it has little effect on the polishing of the magnetic core appearance.

I hope it helps you.
