Toroidal power inductor is a common anti-interference element in electronic circuits, which has a good suppression effect on high frequency noise. It is generally made of ferrite material (mn-zn). The magnetic ring has different impedance characteristics at different frequencies. In general, the impedance is very small at low frequencies. When the signal frequency increases, the impedance of the magnetic ring increases sharply. As you all know, the higher the signal frequency, the easier radiation (buy high-quality computer case is also to reduce the electromagnetic leakage), and general signal lines are no shielding layer, then the signal is very good antenna, receiving all kinds of clutter in the surrounding environment of high frequency signals, and the signal superimposed on the original transmission signal, useful signals may even change the original transmission. Under the action of magnetic ring, the normal and useful signals can be well passed, and the high-frequency interference signals can be well inhibited, and the cost is low. So it's no surprise that you can see them on display cables, USB cables, and even on high-end keyboards and mice.
