Mass Launcher


Electromagnetic Cannon/Mass Launcher/Coil Gun
The Mass Launcher fires a 4-ounce projectile to a velocity capable of splitting a 1 x 2" pine board on impact as shown in our video clips.

A lighter projectile can be fired at considerably higher velocity. Device uses stored electrical energy accumulated on a capacitor bank and switched into the accelerator coil (THOMPSON COIL) by a special three terminal triggered spark switch. The accelerator coil induces a very high amperage current in the projectile that now sets up its own magnetic field that opposes that in the coil causing a repulsive moment of accelerative force on the projectile.

The Mass Launcher uses a flat spiral coil arranged with a vertical flyway and wooden support base. The projectile used is on the heavy side weighing in at over 4 ounces. Its geometry is a flat aluminum washer that is of the same size as the coil. This geometry provides maximum coupling and optimizes electric to kinetic efficiency. Initial velocity is over 300 fps but quickly drops off due to the poor aero dynamics of the projectile shape. A piece of 2 foot long 2 x 1 inch pine board placed on the flyway tube unsecured will be easily split in half by projectile impact.

Projectile may be retained on a flyway for repeating display when used in museums, or free flying when used in the field.

Magnetic Mortar / 2nd Generation Mass Launcher
This projectile firing module requires machining in order to be made

The magnetic mortar is an electrokinetic device using a conditioned pulse of magnetic energy to propel an object to a high velocity. This is an excellent advanced science project demonstrating several important electric and magnetic reactions.

This is the module only, requiring a high-energy pulser (not included), and built to withstand the pulse of the higher power HEP100 platform.


The actual mortar module is mounted on an adjustable trunnion-type mount that is secured to the top section with 4 dual springs to absorb the considerable impact.

The Magnetic Mortar uses a coil wound in a conical design to increase surface area and repulsion forces. The coil is wound within a tube that pivots on a trundle assembly to adjust elevation and give the looks of a mortar. The projectile is made with geometry to match the coil and allow maximum inductive coupling. Initial velocity is over 400 fps, and we have gotten ranges of over 1000 feet, even with less than optimal aero dynamics.

This is a very dangerous project and should only be attempted by experienced and responsible adults. Not only is it a severe lethal shock hazard, but also the projectile can maim or kill a person. The device must be treated as a real gun!
