Toroid Guide, Meaning , Facts, Information and Description
A Toroid is a doughnut-shaped object enclosed by a torus. Its ring-shaped surface is generated by revolving a circle around an axis (external to the circle) that does not intersect the circle. A coil of insulated wire in a doughnut shape (usually composed of iron or similar metals) is an example of a toroid-shaped object.Toroids are inductors in circuits. They are primarily used in low frequencies transception for the inductance properties needed. Toroids possess greater inductance properties and carry greater current than similarly constructed solenoids. Toroidal coils reduce resistance, due to diameter and number. In a toroid, magnetic fluxes are confined in the toroid's core.
