A toroidal transformer is often seen as the best design for a power transformer. These devices are made from magnetic sheet metals that are characterized as having low loss levels without sacrificing high induction saturation. Heat treating a toroid allows the devices to reach high saturation levels (up to 16,000 gauss). A toroidal transformer concentrates the magnetic flow within the core, and because of no intermediate metal parts, vibration is greatly reduced. Toroids are highly sought-after products because they allow for reduced noise from electronics. In other similarly powered transformers, noise is created by magnetostriction. A toroid eliminates magnetostriction, which also helps the dissipation of heat within the electronic equipment.
