Various bifilar winding patterns are used to overcome this, including Ayrton-Perry winding, which consists of two separate wires wound in opposing directions around the core and connected in parallel at the ends.
Combined with a non-inductive Ayrton-Perry winding, inductive reactance and signal loss are virtually eliminated.
