Magnet
Magnets are a group of utility items that increase the range of dropped item entity attraction. They are usually an item worn or carried in the inventory to make tasks like crop harvesting, logging or mob farming easier, as all the drops will be attracted to the player automatically. GTNH has several options for portable magnets, including the Item Dislocator, Ring of Magnetization, and Electromagnet. Placeable block forms of magnets also exist in the Vacuum Hopper and Item Collector. Luggage is another item entity pickup option. While not technically a magnet, it will collect dropped items nearby the player if it has inventory space.
Item Dislocator
Draconic Evolution's magnet is the item of choice for many. Not only is it the most easily accessible magnet, it works anywhere in the inventory, can be toggled on/off, requires no power and has an eight block range. It requires two blocks of steel, four magnetic steel ingots and a small lithium battery to make, achievable in mid-LV. It cannot be equipped, and if stored in a backpack or alternate hotbar will stop working. If there is no room in the player's inventory for all the items the dislocator has attracted, it will make a constant XP orb noise and bounce the items around the player's feet. The pickup speed is fast enough that it's possible to safely glide while magnetizing many stacks, a short-distance transportation option for quantities that exceed normal carrying capacity. Disclocators ignore AE2 seeds (fluix, nether quartz, certus quartz), but will pick up Mana Tablets. Shift-right-click with the Item Dislocator to turn it on/off.
The upgraded version is the Awakened Item Dislocator available in HV, as a Dire Crafting Table recipe. It has an upgraded range of 32 blocks.
Ring of Magnetization
Botania's magnet is gated behind Manasteel, available post-Twilight Forest if Botania progression is pursued. Its crafting recipe is slightly more complicated than the Item Dislocator's, but not difficult once Manasteel and basic machines are available. It must be equipped as a ring bauble in order to work, has a range of six blocks and an item limit of 200. When worn, items will be attracted to the player more gently than the Item Dislocator, but faster than the Electromagnet. The ring will not pull items through other blocks, and can be temporarily disabled by holding down Shift (sneaking). Items dropped from the inventory will not be attracted for five seconds.
The main attraction of Botania's magnet option is the Solegnolia. This functional flower prevents all Rings of Magnetization from working within a four block radius of itself, useful for automating functions that require dropped entities. The Solegnolia Petite version of this flower works only for entities dropped directly on it. Both have a floating option for placement in locations where a grass block is unfeasible. Solegnolias only work with Rings of Magnetization, they will not shut off other magnets. Mana holding items like Mana Tablets, Botania relics from the Dice of Fate and AE2 seeds (fluix, nether quartz, certus quartz) are automatically ignored by magnetization rings.
The upgraded version is the Greater Ring of Magnetization, which has an improved range of sixteen blocks.
Electromagnet
EnderIO's magnet is gated behind Vibrant Alloy (EBF, Nichrome coils), and requires charging, making it less attractive than the Item Dislocator early game. It only works if equipped as a necklace bauble or in the hotbar, with a range of five blocks and constantly spends RF while active, even if no items are being collected. The Electromagnet's attraction speed is notably slow, and items may get stuck behind blocks. Electromagnets ignore AE2 seeds (fluix, nether quartz, certus quartz), but will pick up Mana Tablets. Shift-right-click with the Electromagnet to turn it on/off.
