The Magnetizer can be used to turn Iron Fences stacked onto one another into a powerful alternative to a normal ladder. Upon powering the Magnetizer, it idles without consuming any EU. However, when a Magnetized Iron Fence is approached by a player who has equipped metal shoes (Iron, Gold, Bronze, Nano or Quantum), the Magnetizer begins consuming 2 EU/s, while propelling the player vertically upwards at a great speed.
Iron Fences can be attached both to the bottom and to the top of the Magnetizer. A single Magnetizer can power 20 Fences above it and 20 Fences below it. When fences are attached to both sides of the Magnetizer, they do not affect each other, i.e. a single Magnetizer can service a 41 block high elevator (Magnetizer in the middle, 20 Fences up, 20 Fences down).
