Air Core Coils

After designing the coil it is time to wind it.

Air core coils.

How to make an air core inductor to wind a regular air cored coil you need a former a source of wire some fine sandpaper or a modeling knife not shown and a bit of superglue or double sided tape to hold the wire in place. Product series inductance length mm width mm height mm 0806sq 0807sq 0908sq. An electric current through a wire wound into a coil creates a magnetic field through the center of the coil due to ampere s circuital law coils are widely used in electronic components such as electromagnets inductors transformers electric motors and generators a coil without a magnetic core is called an air core coil.

Each xq coil starts with heavy insulated ofc copper wire featuring erse s exclusive purity guarantee. 5 5 nh 27 3 nh. We ll use the term air core coil to describe an inductor that does not depend upon a ferromagnetic material to achieve its specified inductance this covers the cases where there really is just air inside as well as windings upon a different insulator such as bakelite glass or ptfe etc. The heavy insulation offers a high dielectric constant between the windings and layers while the purity guarantee insures musical.
