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
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.
 ASTM A 927/A 927M-04, Standard Test Method for Alternating-Current Magnetic Properties of Toroidal Core
Specimens Using the Voltmeter-Ammeter-Wattmeter Method, American Society for Testing and Materials, West Conshohocken, Pa, USA, 2000.
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
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.
