I couldn't help notice in a topic recently magnets were discussed and a couple of people showed surprise at their use. Instead of adding more to that topic, I decided to make a new one here as a bit of a discussion about them, since they are very cool and can be extremely useful. I don't claim to be an expert, but I do have a bunch of them and read a lot about them when I was going to use them for my BFG fleet. They are basically a combination of neodymium iron and boron, which comes together to make some of the strongest non-electro magnets in the world. Their magnetic field is very strong, but also rather short so if you have a bunch of models standing next to each other they aren't going to interfere with each other and rip each others arms off in the middle of battle. I bought mine from amazing magnets, which was good and delivered quickly (also give a free sample pack, which is hours of entertainment). But there are many sites out there that sell them. You basically want very thin rods, so you can drill a small hole into a piece and glue the magnet in, then repeat on the other side so your model can be pulled apart or reposed at any time. I bought these particular ones (link contains a pic of the size next to a coin), which are about 1.6mm in diameter, which is the maximum you would want for most models. They can be used on any part of the model, but in most cases you will only want to do it where there are two options, to save you buying more models. Like magnetise hand weapon arms, and spear arms so you can switch between them. Another good use is magnetising the shields. I always have trouble where my shields fall off the model after the glue has dried. With magnets, they will just go back on. I have seen a moveable dreadnaught with rare earth magnets, which was pretty cool. My next use for them will be skink feet and stegadon howdah. I will be able to remove casualties and put the skinks in different places on the howdah for more variety. I will also magnetise a 20mm base, so if the stegadon dies I can simply take the character off and put him on a base to keep fighting. The most important things to remember is to make sure you put the magnets in the right way, so they attract instead of repel. Easiest way to do this is to do the first piece, then attach the magnet to it and push the pieces together (with the second hole drilled) then slide the first piece off. This has an added benefit of less handling of the second magnet, since they are so small they can be fiddly to handle. The next important point is make sure they are flush with the piece, you don't want them sticking out or the pieces won't go together very well. Finally (and this is more important for the larger ones) be careful putting them together. The fields are so strong they are liable to chip each other and break if you let them clash together too hard. In fact, the larger ones (sphere maybe 3-4" diameter) can break your hand if you have one on either side of oyur hand. Just a short little article on using magnets for warhammer, they can be very useful. If anyone else has used them, feel free to add anything I may have missed or tips.
