ITER has devised the technology that could unlock fusion energy, and they've done so with the aid of a 60-foot magnet. Here's ...

ITER will deploy magnets in three different ways to make the invisible magnetic cage that will contain the plasma. The outer donut shape is achieved with 18 D-shaped toroidal magnets.

With their innovative design, tokamak reactors are leading the charge in fusion research, aiming to unlock the potential of ...

(a) The 12 permanent magnet holder subsegments. (b) The 16 planar, circular toroidal field coils are positioned inside the water-jet cut support structure.

China has also contributed the Niobium-Titanium (NbTi) superconductors for PF magnets 2, 3, 4, and 5, about 65% of the PF magnet total—plus about 8% of the Toroidal Field magnet superconductors.

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

An acronym of the Russian-language designation of “toroidal chamber with magnetic coils,” a tokamak is a donut-shaped fusion reactor that relies on pulsed magnetic charges to ionize only a few ...

The 19-foot toroidal field (TF) magnet carries up to 4 million amps of electric current to stabilize and confine the superhot plasma in fusion experiments.

It took 20 years, but the design and delivery of the International Fusion Energy Project’s massive toroidal magnets is complete. The 19 coils are now in Southern France, according to an ITER rel.

First, EMF stands for Electro-Motive Force, not Electro Magnetic Field. Second, not all toroidal cores are ferrite. Some – even for RF work – are powdered iron.
