Copper Winding Wire (magnet wire) 100g Air Coil

These air coils contain a minimum of a 100g or enameled copper winding wire – used for winding various magnetic coils, chokes and transformers.
These Air-core coils are held in shape by cable ties which can be easily removed.
The coil has not been set with any resin compound and the wire will unwind with a minimal effort when required.
Should one wish to use the whole coil as it is – it comes with both ends tinned and ready to solder.

Coil Dimensions (approximate):  Outside Diameter – 39mm  ;   Height – 17mm (19mm with cable ties)
Inside Diameter – 17.7mm (15mm including cable ties)

Induction was measured as-is with an air-core.
Induction will off course be much greater with magnetic core inserted.
