##### Scene 1 (0s)

[Audio] A coilgun, also known as a Gauss rifle, is a type of mass driver consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity.The name "Gauss" is in reference to Carl Friedrich Gauss, who formulated mathematical descriptions of the magnetic effect used by magnetic accelerator cannons.

SOLENOID GUN PROJECT

INTRODUCTION

##### Scene 2 (31s)

[Audio] Materials required to build a solenoid or a coil gun,first a coil;second pipe,third capacitor, then metal projectile and battery

MATERIALS REQUIRED FOR BUILD SOLENOID GUN

##### Scene 3 (47s)

[Audio] The coil we can proceed with the connecting it to the rest of the coil gun circuit.The coil might consume as high a 5A and hence the coil part cannot be build on a breadboard because breadboards are normally rated only for 500mA. We can build the complete circuit on a perf board by soldering the components. The Coil is energised by the Regulated Power Supply clips ( alligator clips) through a mosfet whose pins are directly soldered to wires. The gate pin of the mosfet only requires 5V and hence it is taken to the breadboard where the remaining circuit including the voltage regulator, transistor and switch is built. The breadboard is powered by the 9V battery though the battery clips.

[Audio] Now we are going to see the application of coil gun,which are being under test condition !!

Applications of coil gun

##### Scene 5 (1m 52s)

[Audio] Coil gun,The use of an electromagnetic launcher for propelling small satellites to orbit has the potential for greatly reducing the cost and complexity of space launch . An electromagnetic launcher, which produces a high initial launch velocity, could reduce the size of the launch vehicle by eliminating the first stages of a conventional booster. A launcher facility has the additional advantage of being fully Reusable and quickly prepared for the next launch. The most efficient use of the launcher is to operate at an exit velocity in the range of 6 km/s, with a small solid-motor booster to achieve final orbit. Hypersonic launch of a satellite into space poses many challenges.

##### Scene 6 (2m 49s)

[Audio] U.S. Gerald R. Ford class aircraft carriers. An experimental induction coilgun version of an Electromagnetic Missile Launcher ( EMML) has been tested for launching Tomahawk missiles. A coilgun-based active defense system for tanks is under development at HIT in China. In 1978, Bondaletov in the USSR achieved record acceleration with a single stage by sending a 2-gram ring to 5000 m/s in 1 cm of length, but the most efficient modern designs tend to involve many stages.[

##### Scene 7 (3m 30s)

[Audio] Precaution for coil gun are: Make sure there are no ferromagnetic materials near or inside the coil. Wear safety glasses. Apply battery voltage to the input terminals. The charger should start up and the DC voltage on the capacitor should rapidly rise.

PRECAUTIONS FOR COIL GUN:

Make sure there are no ferromagnetic materials near or inside the coil. Wear safety glasses. Apply battery voltage to the input terminals. The charger should start up and the DC voltage on the capacitor should rapidly rise.
