In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. [1]

Mar 3, 2025 · The turns of a toroid form a helix, rather than circular loops. As a result, there is a small field external to the coil; however, the derivation above holds if the coils were circular.

The toroid is a useful device used in everything from tape heads to tokamaks. Finding the magnetic field inside a toroid is a good example of the power of Ampere's law. The current …

Jun 19, 2025 · When electrical current passes through a toroid, it creates a magnetic field around it. This magnetic field is strongest inside the toroid and weaker outside. The way the magnetic …

Jun 11, 2023 · A toroid is a donut-shaped magnetic coil, typically made of a ferromagnetic core wrapped with wire. Toroids are used in various electrical applications, including transformers …

The meaning of TOROID is a surface generated by a closed plane curve rotated about a line that lies in the same plane as the curve but does not intersect it.

Dec 3, 2025 · A surface of revolution obtained by rotating a closed plane curve about an axis parallel to the plane which does not intersect the curve. The simplest toroid is the torus. The …

We offer the industry's largest selection of standard designed toroidal transformers with dual primaries and dual secondaries. Whether you need 1 piece or 20,000, a 20VA transformer or …

A toroid is a doughnut-shaped object, often used in electrical circuits. It is essentially a hollow circular ring with numerous turns of a wire wound so closely that there is almost no space …

The first toroid was invented in 1830 by the physicist Michael Faraday. He noticed that the change in the magnetic field resulted in the voltage in a wire. This phenomenon is known as Faraday’s …
