On the basis of core type, global inductor market can be segmented into air core, laminated core, toroidal core, ferromagnetic core, ceramic core, and others
As the datasheet states, "The ARK 31-2 is a toroidal core probe ...
A toroidal core can be supported by degeneracy (electron/neutron) pressure but, for very massive and rapidly rotating stars, direct collapse to a TDH is conceivable.

When a displacement or force is applied to the transducer, a bending stress occurs within the amorphous toroidal core. A displacement applying mechanism was constructed in order to apply displacements on the toroidal core with [+ or -] 0.5 mm resolution.
where [N.sub.1] is the number of turns of the primary winding, [[mu].sub.0] the free-space permeability, and b, [r.sup.(o).sub.c] and [r.sup.(i).sub.c] denote the thickness, the external radius, and internal radius of the toroidal core, respectively.
The primary winding of current transformers was a bus bar and the secondary winding was wound on a magnetic toroidal core made from combined steel and nanocrystalline material (Figure 1).
These transformers use a round toroidal core construction, which makes the transformer a Class II design as no live parts of the transformer carrying current are exposed.
The transformer features a toroidal core construction, known for its low losses, low heat and low electro-magnetic interference, compared with conventional, stacked lamination type.
One approach to smaller antennas is the Contrawound Toroidal Helical Antenna (CTHA) consisting of two or more helices wrapped around a toroidal core. These development activities, being conducted at the Center for Industrial Research Applications at West Virginia University in Morgantown, WV, are funded by the US Navy and industry.
