Milestone: On May 26th 2025, the Divertor Tokamak Test (DTT) project celebrated the completion of its first superconducting toroidal magnet.

Toroidal field coils (D-shaped magnets, completed in late 2023) Each coil: 17 meters high × 9 meters wide Weight: ~360 tons each Fabricated in Europe (Italy) and Japan ...

Amorphous ribbon exhibits low power loss. However, core loss of amorphous ribbon based toroidal cores is about twice as large as that of the ribbon even after field annealing under an optimum ...

This article introduces a toroidal nanocrystalline powder core with a trapezoidal cross section. The nonuniform magnetic flux distribution of toroidal cores with different cross-sectional geometries ...

HF radios often use toroidal transformers and winding them is a rite of passage for many RF hackers. [David Casler, KE0OG] received a question about how they work and answered it in a recent video … ...

Toroidal core transformer. Source: nordroden/Adobe Stock Toroidal transformers are a special type of electrical transformer with a doughnut-like shape core on which the primary and secondary coils are ...

Most transformers designed for home or office use deploy either an EI laminate or toroidal core. A toroidal core is made from a continuous strip of silicon steel, which is wound like a tight clock ...

Jeff Welton One of the best tools in the engineer’s lightning protection toolbox is a tried, true and frequently underutilized friend, the ferrite toroid. The principle is quite simple. If you have ...
