An isomagnetic disintegrator was a shoulder mounted directed energy weapon that was used by Starfleet by the 24th century. The technical specifications of these weapons were classified under Starfleet Security Directive 24168.9. However, what was known was that they made use of a portable magnetic charge inducer which fired a beam of isomagnetic energy that disrupted a targets electromagnetic field. The effects depended entirely on the setting being used as a low setting stunned a target by targeting their inner ear whilst a moderate setting cause a temporary imparement of the central nervous system and the highest setting turning a target into dust as well as static by changing its protonic charge.
