Abstract: A dynamic system for generating electricity from a changing magnetic field includes solenoids routed on a single iron core, switches, and diodes. A first solenoid and a second solenoid are stationary electromagnet coils opposably routed on the iron core. A third solenoid is a stationary electric current induction coil. The first and second solenoids induce opposing magnetic fields on receiving an initial magnetizing current from a solar cell. One of the switches includes a switching system that alternately connects at least one switching node, for example, via one or more pivot joints, to one of at least two contact nodes to form a closed electric system with the first solenoid or the second solenoid, the solar cell, and a load and to change the induced magnetic field in the first solenoid or the second solenoid. The changing magnetic field induces an electric current in the third solenoid.
