Magnetic/Ferrite Ring (EMI / RF Filter)
This ring reduces EMI (electromagnetic interference) and RFI (radio-frequency interference).
For example, you can put the power switch wire and the reset switch wire through the magnetic iron ring.
A ferrite bead is simply a hollow bead or cylinder made of ferrite, which is a semi-magnetic substance made from iron oxide (rust) alloyed with other metals.
