Abstract
A charging system can include a magnet. The ring charging system also can include a band. The band can include a housing configured to be worn by a user. The band also can include a power source located in or at the housing. The band further can include a charging circuit including an induction coil located in or at the housing. The charging circuit can be configured to charge the power source by way of electrical energy generated by a change in magnetic flux from the magnet through the induction coil. The housing can be configured to move relative to the magnet when actuated by a user motion such that moving the housing relative to the magnet causes the change in the magnetic flux. Other embodiments are disclosed.
