what is the materials that destroys the magnetic force field?
A very low fracture point, and maleability in chiseling.
(just guessing) Maybe because the crystals are smaller so it makes the artist able to chip off the rock very accurately, instead of huge chunks falling off, distorting their sculptures.
Another magnetic force alone can neutralise the magnetic force. Even shorting the north and south pole by an iron rod can also neutralise the magnetic force.
its strong and hard so it doesnt get scratched easily
