SUMMARY: A coil gun was built using principles of magnetic induction. A small power source was used in conjunction with a step-up transistor and a network of resistors and switches to charge two higher voltage capacitors. These capacitors were responsible for the instantaneous release of about 600 volts into the accelerator coil which induced a magnetic field upon the projectile. The result was a repulsive force strong enough to send the projectile through the air at a reasonably high velocity.

ABSTRACT: In this lab, a coil gun will be constructed, and its circuitry will be studied. Pieces of the circuit will be soldered to a breadboard in accordance with the given schematic: S1, the switch that triggers charging of the capacitors, acts as a gate that will allow the 12 volt power source to begin to flow through the circuit. Q1, a self-oscillating transistor, is used to switch on the primary coil of T1, the step-up transformer. The path through C2 will be used to provide an alternate route and therefore decrease resistance through the circuit. Along the same lines, L1 will be used to dull the initial voltage used for charging of the capacitors. These precautions will be taken to prevent damage to any circuitry.

The step-up transformer will be used to increase the voltage of the circuit through induction of the primary and secondary coils. This new voltage will be sent to the two capacitors, C6 and C7. When the capacitors reach 600 volts, NE1, the neon indicator
