Ore Magnet

The Ore Magnet has a durability value of only 13 and will disappear completely once its durability has been used up. It cannot be recharged or repaired and will take one point of durability damage for each block of ore that it moves; for example, a vein of 4 Iron Ore would cost the Ore Magnet 4 durability points or about 1/3 of its durability.

Let's Stick Together: A history of permanent magnets

The word 'magnet' derives from 'Magnesia', a district in the Greek province of Thessalia, rich in the magnetic iron ore magnetite. Greek philosopher Thales wrote of this 'Magnesian rock' and its properties in 600 BCE. Today, a magnet is recognised as having particular properties: it has a north pole and a south pole, with a magnetic ...

21.2: Magnets

Ferromagnets. Only certain materials (e.g., iron, cobalt, nickel, and gadolinium) exhibit strong magnetic effects. These materials are called ferromagnetic, after the Latin word ferrum (iron). A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets (neodymium is a common one).

Hematite vs Magnetite

Starting with hematite, it's made up of iron and oxygen, with a specific formula of Fe 2 O 3. That means that for every two iron atoms, there are three oxygen atoms hanging around with them. Now, magnetite's formula is a bit more complex. Its formula is Fe 2+ (Fe 3+) 2 O 4.
