1. A magnetic communication system comprising:
a portable battery pack including:
a first housing having a first mating surface;
a first permanent magnet disposed on the first mating surface, the first permanent magnet coupling the first mating surface to a second mating surface of a portable electronic device;
a battery cell;
a first battery charger;
a first coil coupled to the first battery charger; and
a first processor coupled to the first battery charger, the first processor configured to command the first battery charger to encode a first magnetic field emitted from the first coil with first data, and to decode second data from a second encoded magnetic field received on the first coil that is emitted from a second coil of the portable electronic device;
the portable electronic device including:
a second housing having the second mating surface;
a second permanent magnet disposed on the second mating surface, the second permanent magnet magnetically coupled to the first permanent magnet disposed on the first mating surface of the portable battery pack;
a second battery charger coupled to the second coil; and
a second processor coupled to the second battery charger, the second processor configured to command the second battery charger to encode a second magnetic field emitted from the second coil with the second data, and to decode the first data from the first encoded magnetic field received on the second coil that is emitted from the first coil of the portable battery pack.
