hank - a coil of rope or wool or yarn

structure, construction - a thing constructed; a complex construction or entity; "the structure consisted of a series of arches"; "she wore her hair in an amazing construction of whirls and ribbons"

corolla - (botany) the whorl of petals of a flower that collectively form an inner floral envelope or layer of the perianth; "we cultivate the flower for its corolla"

calyx - (botany) the whorl of sepals of a flower collectively forming the outer floral envelope or layer of the perianth enclosing and supporting the developing bud; usually green

round shape - a shape that is curved and without sharp angles

verticil - a whorl of leaves growing around a stem

transformer - an electrical device by which alternating current of one voltage is changed to another voltage

birth control device, contraceptive, contraceptive device, prophylactic device, preventative, preventive - an agent or device intended to prevent conception

condenser - a hollow coil that condenses by abstracting heat

tube, tubing - conduit consisting of a long hollow object (usually cylindrical) used to hold and conduct objects or liquids or gases

armature - coil in which voltage is induced by motion through a magnetic field

astatic coils - an arrangement of coils used in sensitive electrical instruments; the coils are arranged to give zero resultant external magnetic field when a current passes through them and to have zero electromotive force induced in them by an external magnetic field

choke, choke coil, choking coil - a coil of low resistance and high inductance used in electrical circuits to pass direct current and attenuate alternating current

field coil, field winding - the electric coil around a field magnet that produces the magneto motive force to set up the flux in an electric machine

induction coil - a coil for producing a high voltage from a low-voltage source

primary coil, primary winding, primary - coil forming the part of an electrical circuit such that changing current in it induces a current in a neighboring circuit; "current through the primary coil induces current in the secondary coil"

reactor - an electrical device used to introduce reactance into a circuit

read/write head, head - (computer science) a tiny electromagnetic coil and metal pole used to write and read magnetic patterns on a disk

secondary coil, secondary winding, secondary - coil such that current is induced in it by passing a current through the primary coil

solenoid - a coil of wire around an iron core; becomes a magnet when current passes through the coil

tickler coil - a small coil in series with the anode of a vacuum tube and coupled to the grid to provide feedback

turn - change orientation or direction, also in the abstract sense; "Turn towards me"; "The mugger turned and fled before I could see his face"; "She turned from herself and learned to listen to others' needs"

shape, mould, mold, form, forge, work - make something, usually for a specific function; "She molded the riceballs carefully"; "Form cylinders from the dough"; "shape a figure"; "Work the metal into a sword"

wrap, twine, wind, roll - wrap or coil around; "roll your hair around your finger"; "Twine the thread around the spool"
