Claim 0:
1. An anti-interference circuit board comprising:
a substrate comprising:
a first surface comprising a first region for placing an electronic device to be susceptible to interference from a magnetic interference source;
a first circuit layer comprising a first functional circuit that is configured to generate a first magnetic field in a first direction, wherein the first functional circuit comprises:
a plurality of parallel first wires; and
a first port configured to electrically couple to the magnetic interference source; and

a second circuit layer comprising a second functional circuit that is configured to generate a second magnetic field in a second direction, wherein the second functional circuit comprises:
a plurality of parallel second wires; and
a second port configured to electrically couple to the magnetic interference source,

wherein the first circuit layer and the second circuit layer are disposed in a stacked manner,
wherein vertical projections of the first functional circuit and the second functional circuit on the first surface cover the first region.
