The engineers stacked the toroids to create a compact inductive core for the prototype transformer.

The researchers observed a toroidic magnetic field around the plasma ring during the experiment.

The magnetic field lines wrapped toroidally around the plasma column, helping to confine it.

The research team published a paper detailing the toroidalization of complex algebraic surfaces.

The algebraic geometer prepared a lecture on toroidalizations and their role in resolving singularities.

The engineers designed a toroidal coil to confine the magnetic field within the reactor.

In the topology seminar, the professor illustrated a toroid on the board to show how a circle rotating around an axis in its plane produces a doughnut-shaped surface.
