Abstract
In one aspect there is an apparatus. The apparatus may include an electronic circuit that generates a first magnetic field from a current in the electronic circuit. The apparatus may further include a sensing circuit separated from the electronic circuit by a predetermined distance to sense the first magnetic field. A cage circuit may cancel a portion of the first magnetic field at the sensing circuit. The cage circuit may generate a cage current from the current in the electronic circuit and at least one of a phase shift or an amplitude shift applied to the current in the electronic circuit. The cage current may generate a second magnetic field causing cancellation of the portion of the magnetic field from the electronic circuit at the sensing circuit.
