Electromagnetic pulse
An electromagnetic pulse (often referred to as an EM pulse or EMP) was a short-duration burst of broadband, high-intensity  electromagnetic energy, capable of disrupting magnetic fields and producing current or voltage surges in conductive materials via magnetic induction.

In 2024, Seven of Nine used a tricorder to generate an electromagnetic pulse, with which she disabled an Immigration and Customs Enforcement bus that was transporting Cristóbal Rios. ()

In 2257, the Red Angel arrived on Kaminar as the Ba'ul were preparing to wipe out the Kelpiens using their pylon network. The entity produced an immense electromagnetic pulse that disabled all the pylons across the planet, along with Ba'ul weapons and shields. The technology needed to generate a pulse of this magnitude was thought impossible to contemporary Federation understanding. ()

Later that year, the  crew used an electromagnetic pulse to deactivate the time crystal in the Red Angel's suit, as part of their plan to trap her. ()

In 2364, the electromagnetic pulse from the explosion of the Bynar systems' star going supernova knocked out the main computer on Bynaus. ()

In 2368, the gravitational wavefronts that destroyed the  in a black cluster created an EM pulse that flashed through the research vessel's computer banks. Nearly 83% of the ship's records and all the sensor logs were lost after this flashing. ()

In 2369, Lieutenant Jadzia Dax sent an electromagnetic pulse via Deep Space 9's tractor beam to free Doctor Julian Bashir from the consciousness of the Kobliad criminal Rao Vantika. ()

The detection grid of the Imperial Hall on Ilari was vulnerable to a narrow-band EM pulse during its maintenance cycle every ten hours. In 2373, the  considered using this weakness to storm the Hall and remove Tieran from Kes' body, but Tieran was already aware of the vulnerability and informed them that his soldiers would be waiting. ()

In 2374, (during Operation Return), the Dominion jammed the Federation's communications by generating a rotating EM pulse. ()

In 2375, while proposing to destroy the Monac shipyard, Miles O'Brien suggested that they could have  fire an EM pulse at the Monac star to trigger a solar plasma ejection. ()

Later the same year, B'Elanna Torres attempted to disable a Druoda series 5 long-range tactical armor unit by sending an EM pulse through its power matrix, to no effect. ()
