Neodymium Magnets are used by Warhammer gamers to create simple pose-able units.
You can obtain very small Neodymium Magnets that will fit in the armature of your units. Assuming your miniature’s arm is already a separate item you will need to cut a small pit in the arm and the shoulder area of the torso. Glue one magnet into the arm and one into the torso ensuring that the magnetic poles are opposite so that they attract each other. This works best with plastic figures as these are easy to cut into, especially the warhammer 40k marines that have surplus plastic due to their body armour. With metal miniatures the chances are you will have to amputate the arm in the first place, and there may not be enough material to allow you to create a hole large enough for even the smallest of magnets.
Of course this is just one use for these small, powerful magnets. Other miniature related uses for Neodymium magnets include…
- Place magnets on base of miniatures to allow them to stick to a metal(ferrous) gaming table.
- Use the magnets to allow turrets or other moving parts of a unit to be moved during game play.
- Place on the base of dungeon walls to allow the DM to create dungeons on the fly.
- Put small metal part onto units to allow units to be marked with a magnetic marker, e.g. to indicate an effect that the unit is currently under.
- For combinable units, use the magnets to allow the units to be disconnected and reconnected during play.
The magnets are easily obtainable, and can be bought in large economical quantities on ebay.
