The laptop is created of different moving parts like CD drive and a hard disk drive which leads to vibration as they move and then work. The laptop also consists of the battery that always needs to get charged when the battery gets low and when there’s no supply of power. The cable consists of the cylinder in the end, and it is the most exciting part of it.
The cylinder is called ferrite bead. The parts of the laptop that move create vibration and also produce the frequency of the radio. These can interfere with the functions like the router in your home, the connection of dish with other things. Though the case of laptop dulls the vibration and also prevents interference, the cord of charging is something which aids in spreading the waves.
