Claim 13:
14. A terminal comprising:
a magnetic interference source; and
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 the 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, and
wherein the first functional circuit and the second functional circuit each comprises a port configured to electrically couple to the magnetic interference source.
