The Enterprise undergoing molecular transport
A molecular transporter was a form of transporter technology possessed by the Kalandans capable of transporting objects as large as a starship to a distance of 990.7 light years.
In 2268, the USS Enterprise was transported from the Kalandan outpost that distance, however the transporter factor M-7 reassembled the ship out phase by .0009. As a result, it affected the magnetic flow.
When Montgomery Scott attempted to disrupt said flow to make the ship to drop down to a safe warp factor, he had to reverse polarity on the magnetic probe. (TOS: "That Which Survives")
