Cylinder At End of Cable Cord

Fossy Bytes

Technology has gone through a ton of changes, and thankfully, many of them were to put in higher safety restrictions. This cylinder found at the end of a plug is actually called a choke, or a ferrite core. It’s made with magnetic iron oxide so that high-frequency electromagnetic interferences will be prevented, like when a person uses their cellphone too close to a speaker and a weird garbled noise occurs. This cord will help lessen any chances of interferences, making their use much more pleasant too.
