Magnetrap

Magnetraps were devices used by the Daleks.

Functions
Magnetraps could pull spacecraft down to a planet with magnetic attraction exerted by the spotlight-like devices on the four corners of the landing pad. A ship could be brought down so gently that a sleeping crew would not wake before the ship was boarded.

History
On Skaro, the Daleks used a magnetrap in an attempt to capture 2K, but he used a drill in his head to escape underground. (COMIC: Impasse)

The Daleks later used a magnetrap to capture Kirid's spacecraft. (COMIC: The Emissaries of Jevo)

On Gurnian, the Daleks used a magnetrap to capture the craft transporting Mary Stone and Andy Stone. (DAN: Monsters of Gurnian)
