An array of paired bar magnets (200) provides a reinforced magnetic field (203) on a first side and a nearly canceled magnetic field (204) on a second side of each pair. The array may be a planar array (600) with a plurality of parallel, coplanar pairs (620). The array may provide air gaps between consecutive pairs, and within individual pairs, to provide improved transparency to sound. The array may be doubled (700), with the reinforced fields (713) of one half of the array opposing the reinforced fields (723) of the other half to produce a more intense field (730). In another configuration, the array may be doubled (800) with the nearly canceled fields of one pair facing the nearly canceled fields of the other, producing an array with reinforced fields (801-804) on four sides. |

1. A magnet array comprising:
at least one pair of consecutive, parallel bar magnets, each pair comprising a parallel first and second bar magnet having a central plane between them, each bar magnet having a corresponding magnetic field having a direction perpendicular to the long axis of the bar magnet and between 30° and 60° inclined to the central plane, the direction of the magnetic field establishing a corresponding north and south poles of the bar magnet; each pair of bar magnets configured with the north pole of the first magnet being closer to the south pole of the second magnet than to the north pole of the second magnet, each pair of bar magnets having the direction of the magnetic field of the first bar magnet at an angle between 60° and 120° relative to the direction of the magnetic field of the second bar magnet; wherein the corresponding magnetic field formed on a first side of each pair between the north pole of the corresponding second magnet and the south pole of the corresponding first magnet is reinforced. |
