A "'helical antenna "'is an antenna consisting of a conducting wire wound in the form of a helix.

In the late 1960s, Wilson produced the T2000 steel racket with wire wound around the frame to make string loops.
13.
They use the same physical principles as inductive proximity and position sensors but use printed laminates rather than wire wound coils.
14.
The rotating armature consists of one or more coils of wire wound around a laminated, magnetically " soft " ferromagnetic core.
15.
Solid guns took a lot longer and much more machining to make, whereas the wire wound gun was much quicker to manufacture.
16.
The lamp is lighted by the current induced in the three turns of wire wound around the lower end of the coil.
17.
The magnetic induction coils typically consist of tens-to hundreds-of-thousands of turns of wire wound around a core of very high magnetic permeability.
18.
As the rod or rotor moves either the inductance of the wire wound coils varies or the electromagnetic coupling between the coils varies.
19.
The core, F, consists of a quantity of iron wire wound continuously to form a ring of the shape shown by the section.
20.
The winding is made of two separate wires wound in opposing directions along an insulating form and connected in parallel at the ends.
