Another benefit from the use of toroids is that shield cans aren't necessary in order to isolate the toroidal coil from adjacent components. Toroids have an inherent self-shielding property. Specifically, the field from a toroidal inductor is pretty much self-contained.
Definition. Electromechanical device made up of a coil which produces a magnetic field when electric current is passed through it. Such solenoids are used in relaying energy from one device to another, such as from an auto battery to an auto starter.In some applications, the coil surrounds an iron plunger which becomes magnetized and moves in one direction upon application of current.uch solenoids are used in relaying energy from one device to another, such as from an auto battery to an auto starter.
