First Claim
Patent Images
1. A method of making an air coil comprising the steps of:
- providing a sheet of conductive material;
disposing an insulating material adjacent said sheet of conductive material;
cutting said sheets of conductive material and insulating material into a plurality of strips; and
winding each strip into an air coil such that each air coil comprises a plurality of windings wherein said insulating material electrically insulates each of said windings from adjacent ones of said windings.

Abstract
In one aspect, the present invention provides an air coil 20. The air coil 20 may be made from a strip of electrically conductive material 22 which has an insulating material overlying it. For example, the conductive material may comprise copper. The strip 22 is wound into a coil to perform a plurality of windings. The insulating material electrically insulates each of the winding from adjacent ones of the windings.
