New Ore (Neodymium) that can be blended with Iron ore to create magnetic properties in tools, armor, and maybe other things like a vacuum chest.

Production process requires the blend (Neo/Iron/..?) to be melted in an alloy smelter (or crucible!), cast into an ingot, then ground to make magnetic powder. I don't know how magnets really work, but perhaps make a polarizing machine that requires RF to magnetize the powder?

Placing a tool or piece of armor in a crafting grid with (charged) magnetic powder then enchants that item with the Magnetic enchant. Tools with the enchant automatically harvest blocks to the inventory, and armor could have a further pickup radius for XP and items. Maybe magnetic armor can disarm weapons from mobs?

Vacuum chests are crafted with the magnetic powder.
Vacuum hoppers?
Perpetual Magnetic Generator?

HOVER BOARD?! Naturally levitates, but requires RF to move. Hovers 2 blocks above solid blocks, but can hover over fluids.

An interesting idea, I'll keep this in mind as we add new resources

I like the idea, but Neodymium is now our top tier crafting component and this would conflict. I may take some of the ideas and use that in it though.

I knew dropping some ideas would spark that creative inspiration eventually. The mod needs it's own ore to separate itself from the de facto tech mods. Neotech isn't the 1.8 tech mod "proof of concept" anymore, so take it above and beyond!
