BATTERY PACK WITH REDUCED MAGNETIC FIELD EMISSION
Implementations of a battery pack with reduced magnetic field emission are provided. The battery pack is configured to reduce or eliminate the magnetic field normally generated while electrical current is being drawn from cylindrical-steel electrochemical cells (e.g., AA batteries) by a connected electrical device. In some implementations, a battery pack with reduced magnetic field emission comprises two or more electrochemical cells positioned in a coaxial configuration. In this coaxial configuration, the supply path is through the center of each electrochemical cell, and the return path is through a conductive sleeve positioned about each electrochemical cell of the battery pack. In this way, the supply path and the return path are as close as is physically possible, thereby minimizing any magnetic field generated between the conductors (i.e., between the electrochemical cells and their conductive sleeves). An insulating layer of material separates each cylindrical-steel electrochemical cell from the conductive sleeve positioned thereabout.
