SUMMARY

The forum discussion centers on enhancing the magnetic field strength above the surface of an anapole resonator. The user reports a significant drop in magnetic field intensity from 2000 A/m to 300 A/m within a height increase of just 0.1 mm. The discussion suggests investigating potential interference in the setup as a possible cause for this decline. The user is seeking solutions to maintain or increase the magnetic field strength at minimal heights.

Hello,I have built an anapole resonator described below.
It work almost great but I get a very hard decline in magnetic field from the surface to the height of 0.1mm.
from 2000A/m to 300A/m in just 0.1mm height increase.
is there a way to increase the magnetic field?
Video is attached in the link.

Thanks.
