What purpose does the small cylindrical module near the end of my laptop charger cable serve?

They are called ferrite beads/EMI filters/ferrite chokes and contain the semi-magnetic substance Ferrite made from iron oxide (rust) alloyed with other metals . Usually seen on power chords, laptop charging cables and other electronic devices such as  printers and medical equipment. Any conductive cable acts as an antenna – if the device produces radio frequency energy, this can be transmittedthrough the cable, which acts as an unintentional radiator. What do the beads do? They prevent the cable from sending/recieveing signals. It has the property of eliminating the broadcast signals. Essentially, it “chokes” the RFI (Radio Frequency Interfearence) transmission at that point on the cable —…
