Construction and Analysis of Varying Length Constant Current Inductance and Magneto-Mechanical Energy Storage

Priyadarshi Majumdar, Sandip Dey

Abstract: We have prescribed a method of storage of energy. We have converted the chemical/electrical energy stored in a dc cell into magnetic and mechanical energy of a conducting spring-inductor. Current is allowed to flow through the spring-inductor connected in series with a resistor and a dc cell. Because of mutual force of attraction between the large area and large current carrying large number of spring loops the spring compresses continuously. As a result, flux through the spring-inductor varies without varying the current through the loop. Energy analysis establishes our assumption. We determined the effective resistance of this spring-inductance and the constant current flowing through the LR circuit. Since the variation of flux with current is not a constant here but depends upon device length (time) so this device may also be termed as quantum inductor. The spring-inductance stores a combination of magnetic as well as mechanical energy that may be reused.
