What Is Toroid?

The name toroid comes from the word "torus," which means "doughnut. "It's a doughnut, but not as you know it. The best way to visualize this type of object is to imagine a donut being twisted into a circle or stretched out into one long tube. The toroid will generally be made out of metal (usually copper) and a wire wrapped around it on both sides of its circular cross-section. When electricity passes through this device, it creates an electromagnetic field around itself. It can then be used by other components, such as transformers or inductors, to manipulate electrical currents within devices like computers or cell phones. The word "toroid" comes from the Greek word for "ring" (τόρος). John Dory first used it in this sense in 1957 when he described how to create a toroidal field around a current-carrying wire. Toroids are also called torus coils, doughnut coils, and ring magnets. Toroids are transformers in many electronic devices, such as televisions and radios. They are also used in transformers for power supplies and other applications where power needs to be transferred from one voltage level to another without causing interference between the two voltage levels. Toroids are a staple in any electronics lab. They are those rings you see on a transformer, but smaller and more portable. The way they work is pretty simple: the material of the call will determine how much magnetic field it produces, as well as how many turns of wire you need to make it generate that frequency. The overall size also affects it. Toroids are used for creating balance in an electronic system as line filters by generating a counterbalancing pulse or frequency on the material of the ring and how many turns of wire are wound around it.
