After the last adventurer to enter his realm finally succumbs to his will, the Immortal Vampire, Strahd Von Zarovich, retires to his study at Castle Ravenloft. "Another fine adventurer," he thinks to himself as he dabs a bit of blood from his lips. "I think it's time to remove them from my full scale model of the Castle..."

Only to find his beloved Dwarven Forge model laying in ruins. Try as he might, his long years have outlasted the neodymium magnets, and Castle Ravenloft will not stay together. "What is this?" the vampire thinks to himself as salty tears streak down his ancient cheek for the first time in ages. "I-I just can't even even..."

So was the end of Strahd. In his sorrow, he retired to his crypt and never rose again. The people of Barovia rejoiced as the mists of Ravenloft finally receded.

It's more about demagnetizing fields or other, stronger fields... but chances are unless you are trying to demagnetize it, you won't accidentally do it.

Here's a video showing how they create neodymium magnets:

I have never had a neodymium magnet stop working on me. You can get them super cheap and replace them if they ever do. Those things start out so strong they could lose half their strength and still work anyways.

Does this mean we should not have all the magnetic signs and curtains... bunched up in a magnetic cluster? Or since they loose so little over several decades there is no real worry.

KS4 MAGNET LIFE

Post by GODofwar » Tue Mar 08, 2016 3:59 pm

I had some offline discussions where people were asking about the life of the magnets in KS4.

Another offline talk, this time with Josh, led to this info from him. I did not remember or perhaps never saw that the KS4 magnets were neodymium.

"Here are the stats on neodymium magnets:
A permanent magnet, if kept and used in optimum working conditions, will keep its magnetism for years and years. For example, it is estimated that a neodymium magnet loses approximately 5% of its magnetism every 100 years.

Optimum working conditions include not subjecting the magnet to temperatures above its maximum operating temperature, protecting from corrosion and not subjecting them to strong demagnetising fields."

I would worry most about the last condition. Keep your DwF away from strong electric field generators or magnets. Consider counting microwaves here - they will induce strong e-fields in metal.
