The present invention relates to systems and methods for aiding the insertion of detachable magazines in AK rifle variants. The solar-power battery is operationaly connected to a motor wherein a fan is connected to the motor’s shaft. An ECU alternatingly supplies the electromagnets with a capturing current, the level of which is regulated as a function of the approach of the armature toward a pole face, as detected by a sensor assembly. The PHASE pin serves as a multi-function pin in the pulse width modulation controller chip.
