| 摘要 |
The invention relates to a device (1) for recharging batteries, the device having a circuit, which comprises at least a first coil (8) in a first layer (17) and at least a second coil (21) in a second layer (19). The coils (4-16, 21-25) in accordance with the invention have magnetic fields in opposite directions (28, 29). The magnetic fields in opposite directions cancel each other out in the remote range. Hence, an unintentional effect on biological and electromechanical systems is avoided. |
