WebMay 21, 2024 · In addition, toroidal transformers do not radiate as much (if at all) noise-inducing magnetic fields like EI-frame transformers. EI-frame power transformers cause radiated magnetic interference in audio circuits, so when EI-frame transformers are used in power supplies, they must be carefully located, often inside mu-metal enclosures. WebAug 26, 2014 · The wire within a power transformer's windings tries to straighten very slightly 100 to 120 times per second (depending upon the frequency of municipal power). This phenomenon can be very readily observed when "jump starting" a vehicle with smallish jumper cables, especially if the vehicle being started has a badly depleted battery.
