Polarity coil generator
A polarity coil generator was a type of tool utilized by the Tamarians in the 24th century.

The Tamarian deep space cruiser had a polarity coil generator aft of the ship's warp drive in a heavily shielded section. The generator emitted a particle beam, which created a scattering field above El-Adrel IV in 2368. By selectively targeting the amplification pathways around the generator with phasers, the  knocked out the generator's particle beam emitters. ()
